Formal invitations in Korean often use expressions such as 「초대합니다」 (invite) and 「참석해 주시겠습니까?」 (Would you be willing to attend?). When you cannot attend, you can first say 「초대해 주셔서 감사합니다」 (Thank you for the invitation), then politely decline with 「참석이 어렵습니다」 (I'm unable to attend). All of these expressions are polite, but their tone varies depending on who you are speaking to.

For example, a company inviting an external speaker will generally need more formal wording. If you're simply inviting a colleague you know well to dinner, however, an overly formal expression may sound awkward. The same applies when responding to a wedding or event invitation. Saying 「못 갑니다」 (I can't go) is grammatically correct, but it may sound too blunt. Choosing the right Korean expressions for formal invitations and polite refusals depends on the relationship between the people involved, the occasion, and whether a clear response about attendance is required.

How to Make a Formal Invitation in Korean: 「초대합니다」「초청합니다」 and 「모시고자 합니다」

Common Korean expressions for formal invitations include 「초대합니다」 (invite), 「초청합니다」 (formally invite), and 「모시고자 합니다」 (would like to respectfully invite you to attend). All three can be used to invite someone to an event, but they differ in tone and context. 「초대합니다」 has a broad range of uses and works for ordinary gatherings, company events, and formal invitations. 「초청합니다」 is more common in formal invitations to lectures and seminars, while 「모시고자 합니다」 conveys respect for the invitee and is suitable for ceremonies or invitations to distinguished guests.

The differences among these expressions are not determined entirely by the invitee's status; the purpose of the invitation also matters. 「초대합니다」 directly communicates an invitation without emphasizing any particular role the invitee will play. 「초청합니다」 is often used when an organizer invites a speaker, expert, or external guest, usually with an explanation of the person's role or purpose for attending. 「모시고자 합니다」 combines the honorific verb 「모시다」 with 「-고자 하다」, which expresses intention, to convey the desire to welcome someone respectfully.

For example, 「초대합니다」 sounds natural when a company is hosting a general networking event. If the company wants to invite a professor to speak at a seminar, it can use 「초청하고자 합니다」. For a formal ceremony where distinguished guests are invited to attend, 「모시고자 합니다」 is appropriate. However, formal occasions do not necessarily require the latter two expressions, and the three are not entirely interchangeable or mutually exclusive. The choice depends on the event's nature, the relationship between the invitee and the organizer, and the tone the invitation is intended to convey.

• Example: 이번 행사에 여러분을 초대합니다.
  Romanization: i-beon haeng-sa-e yeo-reo-bu-neul cho-dae-ham-ni-da.
  Translation: We invite you all to this event.
  「초대합니다」 communicates an invitation directly. Its tone is formal without being excessively stiff. This sentence works well in general event announcements or invitations and does not particularly emphasize the invitees' status.
• Example: 김 교수님을 특별 강연의 연사로 초청하고자 합니다.
  Romanization: gim gyo-su-ni-meul teuk-byeol gang-yeo-nui yeon-sa-ro cho-cheong-ha-go-ja ham-ni-da.
  Translation: We would like to invite Professor Kim to speak at a special lecture.
  「초청하고자 합니다」 expresses the intention to extend a formal invitation. Combined with 「연사로」 (as a speaker), it clearly communicates the purpose of the invitation. This expression is common in emails from organizers contacting professors, experts, or external speakers.
• Example: 귀빈 여러분을 기념식에 모시고자 합니다.
  Romanization: gwi-bin yeo-reo-bu-neul gi-nyeom-si-ge mo-si-go-ja ham-ni-da.
  Translation: We would be honored to welcome our distinguished guests to the commemorative ceremony.
  「모시고자 합니다」 uses the respectful verb 「모시다」 and is more ceremonious than the general expression 「초대합니다」. It is appropriate for commemorative ceremonies and formal invitations to distinguished guests. If you are merely inviting familiar colleagues to a meal, however, it may create too much distance.

Korean Grammar Rules for Formal Invitations and Polite Refusals: Connecting Nouns, Verbs, and Honorific Endings

How formal invitations and polite refusals are constructed in Korean depends primarily on whether the preceding element is a noun or a verb and which honorific ending follows it. When inviting someone, the invitee generally takes 「을/를」, as in 「교수님을 초청합니다」. To indicate the event someone is being invited to, you can use 「에」, as in 「행사에 초대합니다」.

To turn a verb into a formal expression of invitation, remove 「다」 from its dictionary form and attach 「-고자 하다」, producing forms such as 「초대하고자 합니다」 and 「모시고자 합니다」. To ask whether someone is willing to attend, first change 「참석하다」 to 「참석해」 and then add 「주시겠습니까?」. When expressing gratitude, the verb must also undergo its 「-아/어」 conjugation before 「주셔서 감사합니다」 can be added.

Connection type	Pattern	Example	Note
Invitee	N＋을/를＋초대하다／초청하다／모시다	교수님을 초청합니다	「을/를」 marks the person being invited
Event or occasion	N＋에＋초대하다／초청하다	행사에 초대합니다	「에」 marks the event someone is invited to
Formal intention to invite	Verb stem＋-고자 하다	모시고자 합니다	Remove 「다」 from the dictionary form and attach the ending directly
Formal question	V-아/어＋주시겠습니까?	참석해 주시겠습니까?	Change the verb to 「해」 before adding 「주시겠습니까?」
Conditional request	V-아/어＋주시면 감사하겠습니다	참석해 주시면 감사하겠습니다	「주시면」 consists of 「주시-＋-면」
Gratitude for an invitation	V-아/어＋주셔서 감사합니다	초대해 주셔서 감사합니다	「주셔서」 contains the honorific marker 「-시-」
Noun-based polite refusal	N＋이/가＋어렵습니다	참석이 어렵습니다	「참석」 is a noun and takes a subject particle
Verb-based polite refusal	Verb stem＋-기 어렵습니다	참석하기 어렵습니다	「-기」 nominalizes the action
Indirect negative expression	Verb stem＋-지 못할 것 같습니다	참석하지 못할 것 같습니다	Add 「-(으)ㄹ 것 같다」 after 「-지 못하다」

Formal Invitation Grammar ① | Adding 「을/를」 and 「에」 to Nouns Before Invitation Verbs

「초대하다」「초청하다」 and 「모시다」 are all verbs. When placing the invitee before these verbs, the usual pattern is 「noun＋을/를」. Use 「을」 after a noun ending in a final consonant (batchim) and 「를」 after a noun without one, as in 「교수님을 초청합니다」 and 「귀하를 초대합니다」.

If the sentence also needs to specify the event, you can add 「noun＋에」, as in 「이번 행사에 여러분을 초대합니다」. Here, 「행사에」 indicates the event someone is being invited to, while 「여러분을」 identifies the invitees. The two elements serve different grammatical functions.

When inviting someone to participate in a particular capacity, you can also use 「noun＋(으)로」, as in 「강연자로 초청합니다」 (invite someone as a speaker). 「로」 does not mark the invitee. Instead, it indicates the role in which that person will participate.

• Example: 이번 행사에 여러분을 초대합니다.
  Romanization: i-beon haeng-sa-e yeo-reo-bu-neul cho-dae-ham-ni-da.
  Translation: We invite you all to this event.
  「행사＋에」 identifies the event, while 「여러분＋을」 identifies the invitees. The two nouns take different particles, followed by 「초대합니다」 to complete the invitation.
• Example: 김 교수님을 강연자로 초청합니다.
  Romanization: gim gyo-su-ni-meul gang-yeon-ja-ro cho-cheong-ham-ni-da.
  Translation: We invite Professor Kim to serve as a lecturer.
  「교수님＋을」 identifies the invitee, while 「강연자＋로」 indicates the role the invitee is being asked to take. Both appear before 「초청합니다」, but their particles cannot be exchanged freely.
• Example: 귀빈 여러분을 기념식에 모시고자 합니다.
  Romanization: gwi-bin yeo-reo-bu-neul gi-nyeom-si-ge mo-si-go-ja ham-ni-da.
  Translation: We would be honored to welcome our distinguished guests to the commemorative ceremony.
  「귀빈 여러분＋을」 marks the invitees, while 「기념식＋에」 marks the event. The expression 「모시고자 합니다」 is formed by removing 「다」 from 「모시다」 and attaching 「-고자 하다」.

Formal Invitation Grammar ② | Combining Verb Stems with 「-고자 하다」 and Honorific Request Endings

The expression 「-고자 하다」, commonly found in formal invitations, follows the pattern 「verb stem＋-고자 하다」. For example, removing 「다」 from 「초대하다」 and attaching 「-고자 하다」 produces 「초대하고자 하다」. Changing the final 「하다」 to its formal polite form then produces 「초대하고자 합니다」. The same structure applies to 「모시고자 합니다」, which consists of 「모시-＋고자 합니다」.

When adding 「주시겠습니까?」 or 「주시면 감사하겠습니다」, however, you cannot attach them directly to the verb stem. The verb must first take the 「-아/어」 form. Both 「초대하다」 and 「참석하다」 are 「하다」 verbs, so they become 「초대해」 and 「참석해」 before being followed by 「주시겠습니까?」 or 「주시면 감사하겠습니다」.

The two honorific constructions also differ. 「주시겠습니까?」 consists of 「주다＋-시-＋-겠-＋-습니까?」, while 「주시면」 consists of 「주다＋-시-＋-면」. Therefore, 「참석해 주시겠습니까?」 is a complete question, whereas 「참석해 주시면 감사하겠습니다」 requires the final 「감사하겠습니다」 to form a complete sentence.

• Example: 이번 행사에 여러분을 초대하고자 합니다.
  Romanization: i-beon haeng-sa-e yeo-reo-bu-neul cho-dae-ha-go-ja ham-ni-da.
  Translation: We would like to invite you all to this event.
  Remove 「다」 from 「초대하다」 and use 「초대하＋고자 하다」 to form 「초대하고자 합니다」. You cannot write 「초대해고자 합니다」 because 「-고자 하다」 attaches directly to the verb stem.
• Example: 다음 주 행사에 참석해 주시겠습니까?
  Romanization: da-eum ju haeng-sa-e cham-seo-kae ju-si-get-seum-ni-kka?
  Translation: Would you be willing to attend next week's event?
  First change 「참석하다」 to 「참석해」, then add 「주시겠습니까?」. The marker 「-시-」 expresses respect toward the invitee, while 「-겠-」 and the formal interrogative ending together form a question about the person's willingness.
• Example: 참석 여부를 알려 주시면 감사하겠습니다.
  Romanization: cham-seok yeo-bu-reul al-lyeo ju-si-myeon gam-sa-ha-get-seum-ni-da.
  Translation: We would greatly appreciate it if you could let us know whether you will attend.
  「알리다」 first changes to 「알려」 before 「주시면」 is added. You cannot write 「알리주시면」 directly; the verb must first undergo its 「-아/어」 conjugation.

Formal Invitation Grammar ③ | Expressing Gratitude with 「-아/어 주셔서」 and Declining with 「이/가 어렵다」 or 「-기 어렵다」

When responding to an invitation, you can express gratitude with 「verb＋-아/어 주셔서 감사합니다」. For example, 「초대하다」 first becomes 「초대해」, followed by 「주셔서 감사합니다」 to produce 「초대해 주셔서 감사합니다」. Here, 「주셔서」 is the contracted form of 「주시어서」 and contains the honorific marker 「-시-」, which conveys respect toward the person extending the invitation.

When declining with 「참석이 어렵습니다」, the construction is 「noun＋이/가＋어렵다」. 「참석」 is itself a noun and ends in a final consonant, so it takes 「이」 to form 「참석이 어렵습니다」. If you use the verb 「참석하다」 instead, remove 「다」 and add 「-기」 to nominalize the action, then attach 「어렵습니다」 to form 「참석하기 어렵습니다」.

Another option is 「참석하지 못할 것 같습니다」, formed with 「verb stem＋-지 못하다＋-(으)ㄹ 것 같다」. First, 「참석하다」 becomes 「참석하지 못하다」. Then 「못하다」 changes to 「못할 것 같다」, followed by the formal ending 「-습니다」. In this construction, 「-지 못하다」 negates the action, while 「-(으)ㄹ 것 같다」 adds a softer, tentative nuance. The necessary conjugation steps cannot be skipped.

• Example: 초대해 주셔서 감사합니다.
  Romanization: cho-dae-hae ju-syeo-seo gam-sa-ham-ni-da.
  Translation: Thank you for inviting me.
  「초대하다」 first becomes 「초대해」, followed by 「주셔서 감사합니다」. You cannot write 「초대하주셔서」 because when 「주다」 functions as an auxiliary verb, the preceding verb must take the 「-아/어」 form.
• Example: 이번 행사에는 참석이 어렵습니다.
  Romanization: i-beon haeng-sa-e-neun cham-seo-gi eo-ryeop-seum-ni-da.
  Translation: I won't be able to attend this event.
  「참석」 is a noun, so it takes the subject particle 「이」 to form 「참석이 어렵습니다」. If you use a verb-based construction instead, you can write 「참석하기 어렵습니다」, using 「-기」 to nominalize 「참석하다」.
• Example: 개인적인 사정으로 참석하기 어렵습니다.
  Romanization: gae-in-jeo-gin sa-jeong-eu-ro cham-seo-ka-gi eo-ryeop-seum-ni-da.
  Translation: I am unable to attend due to personal circumstances.
  Remove 「다」 from 「참석하다」 and attach 「-기」 to form 「참석하기」, then add 「어렵습니다」. Here, 「-기」 nominalizes the action, so you cannot simply write 「참석하다 어렵습니다」.
• Example: 이번에는 참석하지 못할 것 같습니다.
  Romanization: i-beo-ne-neun cham-seo-ka-ji mo-tal geot gat-seum-ni-da.
  Translation: I'm afraid I won't be able to attend this time.
  First attach 「-지 못하다」 to 「참석하다」, then change 「못하다」 to 「못할 것 같다」 and use the formal ending 「-습니다」. The full construction follows the sequence 「참석하＋지 못하＋ㄹ 것 같다」.

Korean Formal Invitations and Polite Refusals: Business Invitations, Attendance Inquiries, and Courteous Declines

Formal Invitation Usage ① | Using 「초대합니다」 to Invite Someone to an Event

「초대합니다」 is a common Korean expression for invitations. It can be used in event announcements, invitations, private gatherings, and somewhat formal dinners. It directly communicates an invitation to an occasion, with a tone that is formal but not excessively stiff. This makes it suitable for a wide range of situations.

When using 「초대합니다」, the sentence usually specifies the event or the person being invited. For a more courteous tone, you can combine it with words such as 「정중히」 (respectfully). However, 「초대합니다」 primarily extends an invitation. If you need to confirm whether the person is willing to attend, you should add a separate question or request for a reply.

• Example: 이번 행사에 여러분을 초대합니다.
  Romanization: i-beon haeng-sa-e yeo-reo-bu-neul cho-dae-ham-ni-da.
  Translation: We invite you all to this event.
  This sentence is suitable for event announcements or general invitations. 「초대합니다」 communicates an invitation directly without emphasizing the invitees' status or how ceremonial the event is.
• Example: 다음 주 금요일 저녁 식사에 초대하고 싶습니다.
  Romanization: da-eum ju geu-myo-il jeo-nyeok sik-sa-e cho-dae-ha-go sip-seum-ni-da.
  Translation: I would like to invite you to dinner next Friday.
  「초대하고 싶습니다」 expresses the speaker's wish to invite someone more explicitly than 「초대합니다」. It is suitable for private invitations that require a degree of formality without being overly ceremonious.
• Example: 이번 기념행사에 정중히 초대합니다.
  Romanization: i-beon gi-nyeom-haeng-sa-e jeong-jung-hi cho-dae-ham-ni-da.
  Translation: We cordially invite you to this commemorative event.
  Adding 「정중히」 makes the invitation more ceremonious. This is appropriate for commemorative events, formal gatherings, and written invitations.

Formal Invitation Usage ② | Using 「초청합니다」 and 「모시고자 합니다」 to Invite Speakers and Distinguished Guests

When inviting professors, experts, external speakers, or important guests, Korean commonly uses more formal expressions such as 「초청합니다」 and 「초청하고자 합니다」. To show greater respect toward the invitee, you can also use 「모시고자 합니다」, which means something close to "We would be honored to welcome you."

「초청하다」 commonly appears in formal invitations issued by organizers, such as invitations for a speaker to participate in a seminar or an expert to appear as a forum guest. 「모시고자 합니다」 conveys respect for the invitee and often appears in invitations to ceremonies or distinguished guests. Both expressions can be used for formal invitations, but 「모시고자 합니다」 generally places greater emphasis on respect.

• Example: 김 교수님을 특별 강연의 연사로 초청하고자 합니다.
  Romanization: gim gyo-su-ni-meul teuk-byeol gang-yeo-nui yeon-sa-ro cho-cheong-ha-go-ja ham-ni-da.
  Translation: We would like to invite Professor Kim to speak at a special lecture.
  「초청하고자 합니다」 is appropriate when an organizer formally extends an invitation. This sentence specifies both the invitee and the role being offered. It commonly appears in emails contacting external speakers.
• Example: 이번 세미나에 외부 전문가를 초청합니다.
  Romanization: i-beon se-mi-na-e oe-bu jeon-mun-ga-reul cho-cheong-ham-ni-da.
  Translation: We will invite external experts to participate in this seminar.
  「초청합니다」 can be used to announce that an organizer is inviting outside participants to an event. Its formal tone makes it suitable for descriptions of seminars or professional events.
• Example: 뜻깊은 자리에 귀하를 모시고자 합니다.
  Romanization: tteut-gi-peun ja-ri-e gwi-ha-reul mo-si-go-ja ham-ni-da.
  Translation: We would be honored to welcome you to this meaningful occasion.
  Combining 「모시고자 합니다」 with the formal written form of address 「귀하」 makes the entire sentence especially respectful. It is suitable for ceremonial invitations or formal invitations to important guests.

Formal Invitation Usage ③ | Using 「참석해 주시겠습니까?」 to Ask Whether Someone Is Willing to Attend

If you need to confirm someone's willingness to participate when extending an invitation, you can use 「참석해 주시겠습니까?」, meaning "Would you be willing to attend?" This expression is suitable for supervisors, professors, clients, and external business partners, particularly when the person can decide independently whether to participate.

「참석해 주시겠습니까?」 asks directly about the other person's willingness, leaving more room for discussion than simply saying 「참석하세요」 (Please attend). If the two parties know each other well, a softer question such as 「함께해 주시겠어요?」 may also be appropriate. Both use honorific language, but 「-습니까?」 is generally more formal than 「-어요?」.

• Example: 다음 주 세미나에 참석해 주시겠습니까?
  Romanization: da-eum ju se-mi-na-e cham-seo-kae ju-si-get-seum-ni-kka?
  Translation: Would you be willing to attend next week's seminar?
  This formal question asks about the other person's willingness. It is suitable for business emails, lecture invitations, and confirming attendance with external contacts.
• Example: 시간이 괜찮으시면 함께해 주시겠어요?
  Romanization: si-ga-ni gwaen-cha-neu-si-myeon ham-kke-hae ju-si-get-sseo-yo?
  Translation: If your schedule allows, would you like to join us?
  「-시겠어요?」 is less formal than 「-시겠습니까?」 and works well with familiar colleagues or people toward whom you still need to show courtesy.
• Example: 이번 회의에 참석해 주실 수 있으십니까?
  Romanization: i-beon hoe-ui-e cham-seo-kae ju-sil su i-sseu-sim-ni-kka?
  Translation: Would you be able to attend this meeting?
  「주실 수 있으십니까?」 focuses on whether attendance is possible. Rather than directly requesting participation, it asks whether the person's schedule or other arrangements would allow them to attend.

Formal Invitation Usage ④ | Using 「참석해 주시면 감사하겠습니다」 to Express a Polite Hope for Attendance

「참석해 주시면 감사하겠습니다」 frequently appears in formal invitations and business emails. It means "We would be very grateful if you could attend." The expression conveys the hope that the recipient will participate rather than directly insisting on attendance.

「-아/어 주시면 감사하겠습니다」 can also be used with other verbs to make courteous requests. For example, 「알려 주시면 감사하겠습니다」 means "We would appreciate it if you could let us know." When an event requires a headcount, this pattern can be used to ask recipients to confirm their attendance or respond by a specified deadline.

• Example: 바쁘시더라도 참석해 주시면 감사하겠습니다.
  Romanization: ba-ppeu-si-deo-ra-do cham-seo-kae ju-si-myeon gam-sa-ha-get-seum-ni-da.
  Translation: We would be very grateful if you could make time to attend despite your busy schedule.
  This is suitable for formal invitations, but 「바쁘시더라도」 implies that the recipient is being asked to attend even if busy. You can omit this part if you do not want the person to feel pressured.
• Example: 참석 여부를 금요일까지 알려 주시면 감사하겠습니다.
  Romanization: cham-seok yeo-bu-reul geu-myo-il-kka-ji al-lyeo ju-si-myeon gam-sa-ha-get-seum-ni-da.
  Translation: We would appreciate it if you could let us know by Friday whether you will attend.
  This sentence asks the recipient to confirm participation. It is suitable when organizers need to count attendees, arrange seating, or finalize an event guest list.
• Example: 결혼식에 참석하시어 자리를 빛내 주시면 감사하겠습니다.
  Romanization: gyeol-hon-si-ge cham-seo-ka-si-eo ja-ri-reul bin-nae ju-si-myeon gam-sa-ha-get-seum-ni-da.
  Translation: We would be grateful if you could attend our wedding and honor the occasion with your presence.
  「자리를 빛내 주시면」 is a ceremonious expression found in formal invitations. It is appropriate for weddings and ceremonies but less suitable for an ordinary dinner with colleagues.

Polite Refusal Usage ⑤ | Using 「참석이 어렵습니다」 to Clearly State That You Cannot Attend

When you receive a formal invitation and already know you cannot participate, you can use 「참석이 어렵습니다」, which is close in meaning to "I am unable to attend." Although it literally means that attendance is difficult, it is generally understood as a polite refusal when responding to an invitation. It is suitable for business events, meetings, lectures, and other formal occasions.

In a formal reply, you can begin with 「초대해 주셔서 감사합니다」 to express gratitude, then explain that you cannot attend with 「참석이 어렵습니다」. You do not need to provide extensive details. If you have a scheduling conflict, you can use 「일정이 겹쳐」. If you prefer not to disclose the reason, you can use 「개인적인 사정으로」 (due to personal circumstances).

• Example: 초대해 주셔서 감사합니다. 다만 일정이 겹쳐 참석이 어렵습니다.
  Romanization: cho-dae-hae ju-syeo-seo gam-sa-ham-ni-da. da-man il-jeong-i gyeop-chyeo cham-seo-gi eo-ryeop-seum-ni-da.
  Translation: Thank you for the invitation, but I am unable to attend due to a scheduling conflict.
  This sentence expresses gratitude first, then explains why participation is not possible. It is suitable for email replies to business events or formal invitations.
• Example: 개인적인 사정으로 이번 행사에는 참석이 어렵습니다.
  Romanization: gae-in-jeo-gin sa-jeong-eu-ro i-beon haeng-sa-e-neun cham-seo-gi eo-ryeop-seum-ni-da.
  Translation: I am unable to attend this event due to personal circumstances.
  「개인적인 사정으로」 allows you to avoid disclosing excessive personal information while making your decision not to attend clear.
• Example: 초청해 주셔서 감사드립니다. 이번에는 참석하기 어렵습니다.
  Romanization: cho-cheong-hae ju-syeo-seo gam-sa-deu-rim-ni-da. i-beo-ne-neun cham-seo-ka-gi eo-ryeop-seum-ni-da.
  Translation: Thank you for the formal invitation, but I am unable to attend this time.
  「감사드립니다」 is more ceremonious than 「감사합니다」. It is suitable for replying to organizers, external business partners, or invitations to more formal events.

Polite Refusal Usage ⑥ | Using 「참석하지 못할 것 같습니다」 to Decline Gently

「참석하지 못할 것 같습니다」 means "I'm afraid I won't be able to attend" and is more indirect than simply saying 「참석하지 못합니다」 (I cannot attend). It is appropriate when you want to remain courteous without sounding too blunt, such as when responding to invitations from familiar business partners, colleagues, or organizers of general events.

Here, 「-ㄹ 것 같습니다」 gives the entire sentence a softer, tentative tone. However, if you have already decided that you cannot attend, it is better to include information such as 「일정이 있어서」 (because I already have plans) or 「이번에는」 (this time). This helps the recipient understand that you are politely declining rather than still considering the invitation.

• Example: 아쉽지만 이번에는 참석하지 못할 것 같습니다.
  Romanization: a-swip-ji-man i-beo-ne-neun cham-seo-ka-ji mo-tal geot gat-seum-ni-da.
  Translation: Unfortunately, I'm afraid I won't be able to attend this time.
  「아쉽지만」 expresses regret before explaining the inability to attend. This sounds gentler than a direct refusal and is suitable for general events or invitations among colleagues.
• Example: 해당 날짜에는 다른 일정이 있어 참석하지 못할 것 같습니다.
  Romanization: hae-dang nal-jja-e-neun da-reun il-jeong-i i-sseo cham-seo-ka-ji mo-tal geot gat-seum-ni-da.
  Translation: I already have another commitment that day, so I'm afraid I won't be able to attend.
  The sentence clearly explains that another commitment is scheduled for that day. Even with the softer expression 「것 같습니다」, the recipient can understand why attendance is not possible.
• Example: 좋은 기회에 초대해 주셔서 감사합니다. 이번에는 참석하지 못할 것 같습니다.
  Romanization: jo-eun gi-hoe-e cho-dae-hae ju-syeo-seo gam-sa-ham-ni-da. i-beo-ne-neun cham-seo-ka-ji mo-tal geot gat-seum-ni-da.
  Translation: Thank you for inviting me to this valuable opportunity, but I'm afraid I won't be able to attend this time.
  This expression is suitable for responding to business partners or event organizers. It expresses appreciation for the invitation before politely explaining that participation is not possible. There is no need to promise that you will definitely attend next time.

Polite Refusal Usage ⑦ | Using 「사양하겠습니다」 to Formally Decline an Invitation or Proposal

「사양하겠습니다」 means "I will respectfully decline" and can be used to turn down someone's kindness, invitation, or proposal. Whereas 「참석이 어렵습니다」 emphasizes the inability to attend, 「사양하겠습니다」 more directly communicates a decision not to accept the invitation or proposal. The tone is formal, but the refusal itself is comparatively explicit.

「사양하겠습니다」 is appropriate when a formal refusal is required, but it is not necessary in every reply to an event invitation. If you simply cannot attend because of a scheduling conflict, 「참석이 어렵습니다」 will usually sound more natural. Meanwhile, 「거절합니다」 also means to refuse, but it is more direct and can sound harsh in an ordinary response to an invitation.

• Example: 이번 초대는 정중히 사양하겠습니다.
  Romanization: i-beon cho-dae-neun jeong-jung-hi sa-yang-ha-get-seum-ni-da.
  Translation: I must respectfully decline this invitation.
  「정중히 사양하겠습니다」 clearly communicates the decision to decline. It is appropriate for formal written replies, but its tone is more ceremonious than the general expression 「참석이 어렵습니다」.
• Example: 좋은 자리에 초대해 주셨지만 이번에는 사양하겠습니다.
  Romanization: jo-eun ja-ri-e cho-dae-hae ju-syeot-ji-man i-beo-ne-neun sa-yang-ha-get-seum-ni-da.
  Translation: Although I appreciate being invited to such a wonderful event, I must decline this time.
  The sentence first acknowledges the invitation, then uses 「사양하겠습니다」 to communicate the refusal. It is suitable when you want to decline courteously rather than simply explain that the timing is inconvenient.
• Example: 좋은 제안이지만 이번에는 정중히 사양하겠습니다.
  Romanization: jo-eun je-a-ni-ji-man i-beo-ne-neun jeong-jung-hi sa-yang-ha-get-seum-ni-da.
  Translation: Although it is a good proposal, I must respectfully decline this time.
  「사양하다」 can also be used to decline proposals or another person's kindness, not just invitations to events. This sentence is appropriate for clearly turning down a collaboration proposal, job offer, or other formal proposal.

Differences in Tone Between Korean Formal Invitations and Polite Refusals: Which Expressions Could Cause Misunderstandings?

Common Korean expressions for formal invitations include 「초대합니다」「초청합니다」 and 「모시고자 합니다」. All three express an invitation, but their tone and usage differ. 「초대합니다」 works for both general gatherings and formal events. 「초청합니다」 is commonly used when organizers invite speakers or external guests, while 「모시고자 합니다」 conveys particular respect toward the invitee.

When asking someone whether they are willing to participate, there is also a difference between 「참석해 주시겠습니까?」 and 「참석해 주시면 감사하겠습니다」. The former asks directly about the person's willingness, while the latter politely expresses the hope that they will attend. When declining, 「참석이 어렵습니다」「참석하지 못할 것 같습니다」 and 「사양하겠습니다」 can all communicate a refusal, but they do not sound exactly alike. Their implications differ depending on whether the speaker is stating an inability to attend, gently explaining the situation, or formally declining the invitation.

▌「초대합니다」 vs 「초청합니다」 | General Invitations vs Formal Invitations

Both 「초대합니다」 and 「초청합니다」 can mean "invite," but 「초대합니다」 has broader applications. It can be used for dinners with friends, company events, and wedding invitations. 「초청합니다」 appears more often when organizers invite external participants, such as asking a professor to deliver a lecture, inviting an expert to a forum, or requesting a particular guest's attendance at an event.

However, neither expression has an absolute restriction based on the invitee's status. 「초대합니다」 can also be used for formal events, and 「초청합니다」 is not limited to inviting people of higher status. The main difference concerns the nature of the event and whether the speaker wants to convey the tone of a formal invitation.

• Example: 이번 행사에 여러분을 초대합니다.
  Romanization: i-beon haeng-sa-e yeo-reo-bu-neul cho-dae-ham-ni-da.
  Translation: We invite you all to this event.
  「초대합니다」 communicates an invitation directly and is suitable for general event announcements or invitations. The sentence does not specify any particular professional status for the invitees.
• Example: 김 교수님을 강연자로 초청합니다.
  Romanization: gim gyo-su-ni-meul gang-yeon-ja-ro cho-cheong-ham-ni-da.
  Translation: We invite Professor Kim to serve as a lecturer.
  Combining 「초청합니다」 with 「강연자로」 makes it clear that the professor is being invited to participate as a speaker. This sounds more like a formal invitation than an invitation to an ordinary gathering.

▌「초청합니다」 vs 「모시고자 합니다」 | Formal Invitations vs Respectful Invitations

「초청합니다」 focuses on formally inviting someone to participate in an event, while 「모시고자 합니다」 places greater emphasis on respect for the invitee. The verb 「모시다」 itself conveys the ideas of treating someone respectfully, accompanying them, or respectfully welcoming them. As a result, using 「모시고자 합니다」 in an invitation sounds more ceremonious than the general expression 「초청합니다」.

Both expressions can be used to invite important guests, but the choice does not necessarily depend on the person's rank. 「초청합니다」 is appropriate when describing formal arrangements involving speakers or experts. 「모시고자 합니다」 is common in situations that require particular respect, such as ceremonies or invitations to distinguished guests.

• Example: 교수님을 특별 강연의 연사로 초청하고자 합니다.
  Romanization: gyo-su-ni-meul teuk-byeol gang-yeo-nui yeon-sa-ro cho-cheong-ha-go-ja ham-ni-da.
  Translation: We would like to invite the professor to speak at a special lecture.
  「초청하고자 합니다」 expresses the intention to extend a formal invitation. It is appropriate when organizers approach an external speaker, with the emphasis on inviting the person to fulfill a particular role.
• Example: 귀빈 여러분을 기념식에 모시고자 합니다.
  Romanization: gwi-bin yeo-reo-bu-neul gi-nyeom-si-ge mo-si-go-ja ham-ni-da.
  Translation: We would be honored to welcome our distinguished guests to the commemorative ceremony.
  「모시고자 합니다」 directly conveys respect for the invitees. It is particularly suitable for formal invitations, but it may sound excessively ceremonious when simply inviting familiar colleagues to dinner.

▌「참석해 주시겠습니까?」 vs 「참석해 주시면 감사하겠습니다」 | Asking About Willingness vs Expressing Hope

「참석해 주시겠습니까?」 is a formal question that directly asks whether someone is willing to attend. It is appropriate when the person's willingness must first be confirmed, such as inviting a professor to participate in a seminar or asking a business partner whether attending an event would be convenient.

「참석해 주시면 감사하겠습니다」 does not ask a question directly. Instead, it communicates the sentiment, "We would be very grateful if you could attend." It is suitable for formal invitations and emails because it shows that the inviting party hopes the recipient will participate. If a headcount is required, the organizer should still specify a reply deadline or confirmation method separately.

• Example: 다음 주 세미나에 참석해 주시겠습니까?
  Romanization: da-eum ju se-mi-na-e cham-seo-kae ju-si-get-seum-ni-kka?
  Translation: Would you be willing to attend next week's seminar?
  This formal question asks directly about the recipient's willingness to attend. It is suitable for inviting supervisors, professors, or business partners.
• Example: 다음 주 세미나에 참석해 주시면 감사하겠습니다.
  Romanization: da-eum ju se-mi-na-e cham-seo-kae ju-si-myeon gam-sa-ha-get-seum-ni-da.
  Translation: We would be very grateful if you could attend next week's seminar.
  Rather than directly asking whether the recipient will participate, this sentence politely expresses the hope that they will attend. It is appropriate for formal invitations.

▌「참석해 주시겠습니까?」 vs 「참석 부탁드립니다」 | Asking About Willingness vs Requesting Attendance

Both 「참석해 주시겠습니까?」 and 「참석 부탁드립니다」 can be used when inviting someone to an event, but the former asks about the person's willingness, while the latter requests attendance. 「참석 부탁드립니다」 commonly appears in meeting notices, company announcements, and work-related event arrangements. It emphasizes the expectation that relevant people will cooperate by attending.

If the recipient already has an obligation to attend, such as a routine departmental meeting, 「참석 부탁드립니다」 will generally not sound out of place. However, when inviting external speakers or clients who can freely decide whether to participate, 「참석해 주시겠습니까?」 is more appropriate for asking about their willingness.

• Example: 이번 회의에 참석해 주시겠습니까?
  Romanization: i-beon hoe-ui-e cham-seo-kae ju-si-get-seum-ni-kka?
  Translation: Would you be willing to attend this meeting?
  The speaker is asking whether the recipient wishes to participate. This is suitable when consent or confirmation of attendance is needed in advance.
• Example: 이번 회의에 참석 부탁드립니다.
  Romanization: i-beon hoe-ui-e cham-seok bu-tak-deu-rim-ni-da.
  Translation: Please attend this meeting.
  「참석 부탁드립니다」 directly requests attendance and is suitable for workplace notices or internal announcements. If the recipient is not obligated to attend, it may sound somewhat more demanding than a question.

▌「참석이 어렵습니다」 vs 「참석하지 못할 것 같습니다」 | Clear Polite Refusal vs Indirect Wording

Both 「참석이 어렵습니다」 and 「참석하지 못할 것 같습니다」 can be used to say that you cannot attend, but the former is generally clearer while the latter is softer. Literally, 「참석이 어렵습니다」 means that attendance is difficult. In a formal reply, it is usually understood to mean that the speaker has already decided they cannot participate.

「참석하지 못할 것 같습니다」 carries a nuance similar to "I'm afraid I won't be able to attend." The ending 「-ㄹ 것 같습니다」 makes the refusal less direct. However, this does not necessarily mean the speaker is still considering the invitation. If a scheduling conflict or another reason has already been explained, the recipient can generally understand it as a polite refusal.

• Example: 다른 일정이 있어 참석이 어렵습니다.
  Romanization: da-reun il-jeong-i i-sseo cham-seo-gi eo-ryeop-seum-ni-da.
  Translation: I am unable to attend because I already have another commitment.
  The sentence first explains the scheduling issue, then directly uses 「참석이 어렵습니다」. It is appropriate for formal occasions where a clear reply about attendance is required.
• Example: 다른 일정이 있어 참석하지 못할 것 같습니다.
  Romanization: da-reun il-jeong-i i-sseo cham-seo-ka-ji mo-tal geot gat-seum-ni-da.
  Translation: I already have another commitment, so I'm afraid I won't be able to attend this time.
  The reason is still a scheduling conflict, but 「것 같습니다」 makes the sentence more indirect. Because a reason has been provided, it will generally still be understood as a reply indicating that attendance is not possible.

▌「참석이 어렵습니다」 vs 「사양하겠습니다」 | Unable to Attend vs Formally Declining

「참석이 어렵습니다」 primarily explains that someone cannot attend an event, perhaps because of a scheduling conflict, personal circumstances, or other commitments. 「사양하겠습니다」 directly expresses the decision to decline the invitation, conveying something close to "I must respectfully decline this time."

Both expressions can appear in formal replies, but 「사양하겠습니다」 does not necessarily indicate that an objective circumstance is preventing attendance. The person may simply have decided not to accept the invitation. Therefore, 「참석이 어렵습니다」 usually sounds more natural if the issue is simply an inconvenient schedule. If you wish to formally decline an invitation or proposal itself, 「사양하겠습니다」 is an option.

• Example: 이번 행사에는 참석이 어렵습니다.
  Romanization: i-beon haeng-sa-e-neun cham-seo-gi eo-ryeop-seum-ni-da.
  Translation: I won't be able to attend this event.
  This sentence simply states that participation is not possible without specifically expressing a decision about accepting the invitation itself. It is suitable for politely declining attendance at a general formal event.
• Example: 이번 초대는 정중히 사양하겠습니다.
  Romanization: i-beon cho-dae-neun jeong-jung-hi sa-yang-ha-get-seum-ni-da.
  Translation: I must respectfully decline this invitation.
  「사양하겠습니다」 clearly indicates that the invitation will not be accepted. Adding 「정중히」 makes the tone more ceremonious. It may create an excessive sense of distance if used for an ordinary dinner.

▌「사양하겠습니다」 vs 「거절합니다」 | Courteous Refusal vs Direct Rejection

Both 「사양하겠습니다」 and 「거절합니다」 express refusal, but 「사양하다」 conveys the idea of politely declining or turning something down. It is commonly used when courteously declining another person's invitation, proposal, or kindness. 「거절하다」 is the general verb for "refuse" or "reject" and directly states that someone's request or proposal will not be accepted.

The distinction is not merely a matter of formality. Although 「사양하겠습니다」 is a clear refusal, it retains a courteous tone. 「거절합니다」 focuses on the decision to reject. The verb 「거절하다」 is natural in situations where a rejection must be explicitly recorded, such as business reviews or proposal processing. However, using it directly in response to an ordinary event invitation may sound harsh.

• Example: 이번에는 정중히 사양하겠습니다.
  Romanization: i-beo-ne-neun jeong-jung-hi sa-yang-ha-get-seum-ni-da.
  Translation: I must respectfully decline this time.
  The speaker has already decided not to accept the invitation, but 「사양하겠습니다」 maintains a courteous tone. It is suitable for formally declining proposals or invitations.
• Example: 이번 초대를 거절합니다.
  Romanization: i-beon cho-dae-reul geo-jeol-ham-ni-da.
  Translation: I reject this invitation.
  This sentence states the refusal directly without gratitude or a softer explanation. It will usually sound too blunt as a response to an ordinary event invitation, although it is grammatically correct when objectively describing a decision to reject something.

▌How Different Expressions Change the Tone in the Same Situation

Suppose a Korean company is holding a seminar next week and wants to invite an external professor. Although the purpose of the invitation is the same, the speaker's position and intention come across differently depending on whether they use 「초대합니다」「초청하고자 합니다」「모시고자 합니다」 or 「참석해 주시겠습니까?」.

「초대합니다」 informs the recipient that they are invited. 「초청하고자 합니다」 sounds more like a formal invitation being extended by an organizer. 「모시고자 합니다」 adds respect toward the invitee, while 「참석해 주시겠습니까?」 asks whether the person is willing to attend. Using 「참석해 주시면 감사하겠습니다」 shifts the tone toward politely expressing the hope that the person will attend.

Situation 1: Inviting a Professor to Next Week's Seminar

• Example: 다음 주 세미나에 초대합니다.
  Romanization: da-eum ju se-mi-na-e cho-dae-ham-ni-da.
  Translation: We invite you to next week's seminar.
  This is a general formal invitation suitable for an event invitation. Even if the invitee is a professor, a more ceremonious verb is not necessarily required.
• Example: 다음 주 세미나에 초청하고자 합니다.
  Romanization: da-eum ju se-mi-na-e cho-cheong-ha-go-ja ham-ni-da.
  Translation: We would like to formally invite you to next week's seminar.
  「초청하고자 합니다」 conveys a stronger sense of an organizer extending a formal invitation than the simpler 「초대합니다」. It is appropriate when contacting external participants.
• Example: 교수님을 다음 주 세미나에 모시고자 합니다.
  Romanization: gyo-su-ni-meul da-eum ju se-mi-na-e mo-si-go-ja ham-ni-da.
  Translation: We would be honored to welcome you, Professor, to next week's seminar.
  「모시고자 합니다」 emphasizes respect toward the professor. It is suitable for a formal letter intended to respectfully request their attendance.
• Example: 다음 주 세미나에 참석해 주시겠습니까?
  Romanization: da-eum ju se-mi-na-e cham-seo-kae ju-si-get-seum-ni-kka?
  Translation: Would you be willing to attend next week's seminar?
  Unlike the previous three sentences, this directly asks whether the professor is willing to participate. It is suitable when the professor's willingness has not yet been confirmed.
• Example: 다음 주 세미나에 참석해 주시면 감사하겠습니다.
  Romanization: da-eum ju se-mi-na-e cham-seo-kae ju-si-myeon gam-sa-ha-get-seum-ni-da.
  Translation: We would be very grateful if you could attend next week's seminar.
  This sentence politely expresses the hope that the professor will attend without directly requiring an answer about participation. If the guest list needs to be confirmed, a reply deadline can be added.

Now suppose the professor receives the invitation and discovers that they already have another commitment that day. They can politely decline with either 「참석이 어렵습니다」 or 「참석하지 못할 것 같습니다」. Using 「사양하겠습니다」, however, would sound more like formally declining the invitation itself rather than simply explaining a scheduling conflict.

Situation 2: Unable to Attend After Receiving a Seminar Invitation

• Example: 일정이 겹쳐 이번에는 참석이 어렵습니다.
  Romanization: il-jeong-i gyeop-chyeo i-beo-ne-neun cham-seo-gi eo-ryeop-seum-ni-da.
  Translation: I am unable to attend this time because of a scheduling conflict.
  This sentence is suitable when the person already knows they cannot participate. By explaining the reason and clearly stating their inability to attend, they allow the organizer to proceed with other arrangements.
• Example: 일정이 겹쳐 이번에는 참석하지 못할 것 같습니다.
  Romanization: il-jeong-i gyeop-chyeo i-beo-ne-neun cham-seo-ka-ji mo-tal geot gat-seum-ni-da.
  Translation: I'm afraid I won't be able to attend this time because of a scheduling conflict.
  This sounds softer than the previous sentence. Although it uses 「것 같습니다」, the scheduling conflict has already been explained, so the recipient can generally understand that attendance is not possible.
• Example: 이번 초대는 정중히 사양하겠습니다.
  Romanization: i-beon cho-dae-neun jeong-jung-hi sa-yang-ha-get-seum-ni-da.
  Translation: I must respectfully decline this invitation.
  This sentence does not explain why attendance is impossible. Instead, it directly communicates the decision to decline the invitation. Its tone is formal, but it may sound somewhat distant if the two parties already know each other well.
• Example: 이번 초대를 거절합니다.
  Romanization: i-beon cho-dae-reul geo-jeol-ham-ni-da.
  Translation: I reject this invitation.
  Although grammatically correct, this sentence uses 「거절합니다」 directly, making the refusal sound strong. It is generally not recommended as a standalone reply to an ordinary event invitation from an organizer.

Even when the same professor is being invited to a seminar, 「초청하고자 합니다」 is appropriate for formally extending the invitation, 「모시고자 합니다」 for showing particular respect, and 「참석해 주시겠습니까?」 for checking the person's willingness first.

There is also no need to make a refusal unnecessarily long. If you already know you cannot attend, 「초대해 주셔서 감사합니다. 다만 일정이 겹쳐 참석이 어렵습니다.」 communicates both gratitude and a clear response. 「사양하겠습니다」 is more suitable when you wish to formally decline the invitation itself and does not need to replace every expression indicating an inability to attend.

Korean Formal Invitations and Polite Refusals in Context: Examples for Seminars, Dinners, and Weddings

In actual Korean conversations, the tone of formal invitations and polite refusals changes depending on the recipient, the event, and the relationship between the people involved. When inviting professors or external speakers, expressions such as 「초청하고자 합니다」 (we would like to extend a formal invitation) and 「알려 주시면 감사하겠습니다」 (we would appreciate it if you could let us know) are commonly used. If you are simply inviting familiar colleagues to dinner, 「함께하실래요?」 (Would you like to join us?) maintains politeness without sounding overly formal.

Similar distinctions apply when declining invitations. In response to a business invitation, you can begin with 「초청해 주셔서 감사합니다」 (Thank you for the invitation) and then clearly reply with 「참석이 어렵습니다」 (I am unable to attend). With familiar colleagues, 「못 갈 것 같아요」 (I'm afraid I can't make it) sounds more conversational. For invitations to weddings or ceremonies, you can also add congratulations or good wishes after explaining that you cannot attend. These situations do not always require the most formal honorifics. What matters is clearly communicating the invitation or refusal while using language appropriate to the relationship.

▌Situation ① | A Company Invites a Professor to Speak at a Seminar

A：교수님, 다음 달 세미나에 연사로 초청하고자 합니다. 가능하신지 알려 주시면 감사하겠습니다.
　　gyo-su-nim, da-eum dal se-mi-na-e yeon-sa-ro cho-cheong-ha-go-ja ham-ni-da. ga-neung-ha-sin-ji al-lyeo ju-si-myeon gam-sa-ha-get-seum-ni-da.
　　Professor, we would like to invite you to speak at next month's seminar. We would greatly appreciate it if you could let us know whether you are available.

B：초청해 주셔서 감사합니다. 다만 그날은 다른 일정이 있어 강연을 맡기 어렵습니다.
　　cho-cheong-hae ju-syeo-seo gam-sa-ham-ni-da. da-man geu-na-reun da-reun il-jeong-i i-sseo gang-yeo-neul mat-kki eo-ryeop-seum-ni-da.
　　Thank you for the invitation. However, I already have another commitment that day and won't be able to give the lecture.

📌 Grammar Point: 「초청하고자 합니다」 is appropriate when an organizer formally invites an external speaker. Here, 「-고자 하다」 expresses the intention to carry out an action. The following expression, 「가능하신지 알려 주시면 감사하겠습니다」, asks the recipient to confirm their availability rather than directly insisting that they accept. Speaker B first expresses gratitude with 「초청해 주셔서 감사합니다」, then clearly declines the speaking engagement with 「강연을 맡기 어렵습니다」. In this context, 「강연을 맡다」 (to take responsibility for delivering a lecture) is more precise than simply saying 「참석이 어렵습니다」 because the professor was invited as a speaker, not as an ordinary attendee.

▌Situation ② | A Colleague Invites Someone to a Team Dinner

A：내일 저녁에 팀 회식이 있는데, 시간 괜찮으시면 함께하실래요?
　　nae-il jeo-nyeo-ge tim hoe-si-gi in-neun-de, si-gan gwaen-cha-neu-si-myeon ham-kke-ha-sil-lae-yo?
　　We're having a team dinner tomorrow evening. Would you like to join us if you're free?

B：불러 주셔서 감사해요. 그런데 내일은 선약이 있어서 못 갈 것 같아요.
　　bul-leo ju-syeo-seo gam-sa-hae-yo. geu-reon-de nae-i-reun seon-ya-gi i-sseo-seo mot gal geot ga-ta-yo.
　　Thanks for inviting me. Unfortunately, I already have plans tomorrow, so I don't think I can make it.

📌 Grammar Point: 「함께하실래요?」 uses 「-실래요?」 to ask whether someone would like to participate. It is more appropriate for conversations between familiar colleagues than the formal 「참석해 주시겠습니까?」. Adding 「시간 괜찮으시면」 first checks whether the recipient is available, so the invitation does not sound like a work instruction. Speaker B uses 「못 갈 것 같아요」 to gently indicate an inability to attend, while 「선약이 있어서」 (because I already have plans) makes the reason clearer. There is no need to deliberately switch to 「참석이 어렵습니다」 for this type of everyday invitation. Maintaining the polite 「-요」 ending is enough to express courtesy naturally.

▌Situation ③ | Responding to a Wedding Invitation When You Cannot Attend

A：다음 달에 결혼식을 올리게 됐습니다. 참석해 주시면 감사하겠습니다.
　　da-eum da-re gyeol-hon-si-geul ol-li-ge dwaet-seum-ni-da. cham-seo-kae ju-si-myeon gam-sa-ha-get-seum-ni-da.
　　We're getting married next month. We would be very grateful if you could join us for the wedding.

B：초대해 주셔서 감사합니다. 아쉽게도 그날은 참석하기 어렵습니다. 결혼 진심으로 축하드립니다.
　　cho-dae-hae ju-syeo-seo gam-sa-ham-ni-da. a-swip-ge-do geu-na-reun cham-seo-ka-gi eo-ryeop-seum-ni-da. gyeol-hon jin-si-meu-ro chu-ka-deu-rim-ni-da.
　　Thank you for inviting me. Unfortunately, I won't be able to attend that day. My heartfelt congratulations on your marriage.

📌 Grammar Point: 「참석해 주시면 감사하겠습니다」 commonly appears in formal invitations and uses a conditional construction to express the hope that the recipient will attend. In Speaker B's reply, 「초대해 주셔서 감사합니다」 first expresses gratitude, followed by 「참석하기 어렵습니다」 to clearly indicate an inability to participate. The reply ends with 「결혼 진심으로 축하드립니다」 (heartfelt congratulations on your marriage). There is no need to explain extensive personal details when declining a wedding invitation. However, if you already know that you cannot attend, it is best to communicate that decision directly. Responding only with 「생각해 보겠습니다」 (I'll think about it) may leave the couple waiting for an answer and affect seating arrangements or the final guest count.

Additional Usage Notes:

1. 「초대하다」「초청하다」 and 「모시다」 can all be used for invitations, but there is no need to choose the most formal expression every time. 「초대하다」 sounds natural for ordinary dinners and private events. 「초청하다」 is more appropriate for formal invitations involving external speakers or experts. 「모시다」 is commonly used when particular respect toward the invitee is intended. For example, you can say 「강연자로 초청하고자 합니다」 when inviting a professor to speak or 「모시고자 합니다」 when respectfully requesting a distinguished guest's presence at a ceremony. However, 「초청하다」 and 「모시다」 are not distinguished simply by the invitee's rank. The event's format and the relationship between the parties must also be considered.
2. 「참석해 주시겠습니까?」「참석해 주시면 감사하겠습니다」 and 「함께하실래요?」 can all be used when inviting someone, but their functions and levels of formality differ. 「참석해 주시겠습니까?」 directly asks whether someone is willing to attend and is appropriate for formal business invitations. 「참석해 주시면 감사하겠습니다」 expresses hope for attendance and commonly appears in invitations or emails. If a headcount is required, you should also add 「참석 여부를 알려 주시면 감사하겠습니다」 (We would appreciate it if you could let us know whether you will attend). 「함께하실래요?」 is suitable for familiar colleagues and general courteous invitations. Although all three use honorific language, they cannot be substituted freely simply because their meanings are similar.
3. When declining an invitation, the main differences between 「참석이 어렵습니다」 and 「못 갈 것 같아요」 concern formality and speaking style. The former is often used for business events, meetings, and formal invitations that require a clear response. The latter is more conversational and suits familiar colleagues or friends. If you already know that you cannot attend, 「참석이 어렵습니다」 can reduce the likelihood that the recipient mistakenly believes further adjustments are possible. 「사양하겠습니다」 conveys a formal decision to decline an invitation or proposal, so it is not necessarily needed when you are simply unable to attend an ordinary dinner because of a scheduling conflict. Whichever expression you choose, it is best to provide a clear answer once you know you cannot participate. You do not need to promise 「다음에 꼭 가겠습니다」 (I'll definitely go next time) merely to be polite.

Understanding Korean 「초대합니다／모시고자 합니다」 and Japanese 「ご招待します／お招きしたく存じます」

The Japanese expression 「ご招待します」 and the Korean expression 「초대합니다」 both communicate an invitation to an event. They can be used for gatherings, invitations, and generally formal occasions. When inviting speakers, experts, or important guests, Japanese can use 「お招きしたく存じます」, while Korean commonly uses more formal expressions such as 「초청하고자 합니다」 and 「모시고자 합니다」.

However, Japanese and Korean do not express respect in exactly the same way. The Japanese expression 「お招きしたく存じます」 uses humble, courteous language to convey the intention to invite someone. In Korean, 「모시고자 합니다」 expresses the wish to respectfully welcome someone through the verb 「모시다」, which carries a respectful meaning. Both are appropriate for formal invitations, but they should not be understood as translations of identical grammatical structures.

◆ Similar Expressions: 「ご招待します／お招きしたく存じます」

The Japanese 「ご招待します」 can be used for general formal invitations and has a meaning close to the Korean 「초대합니다」. To express the intention to extend a formal invitation, 「お招きしたく存じます」 can be used, although the exact wording may vary depending on the invitee's role. For example, when inviting a professor to give a lecture, Japanese can also use 「ご講演をお願いしたく存じます」 to make the request directly. Korean may use 「강연자로 초청하고자 합니다」. Both convey the purpose of the invitation.

• Example: このたびの交流会に皆様をご招待いたします。
  Kana: このたびのこうりゅうかいにみなさまをごしょうたいいたします。
  Translation: We cordially invite you all to this networking event.
  Korean: 이번 교류회에 여러분을 초대합니다.
  Romanization: i-beon gyo-ryu-hoe-e yeo-reo-bu-neul cho-dae-ham-ni-da.
  The Japanese 「ご招待いたします」 uses humble and courteous wording, making it more formal than the general 「招待します」. The Korean 「초대합니다」 can already be used for formal invitations, so an additional honorific construction is not necessary merely to match the Japanese 「いたします」.
• Example: 来月のセミナーに講師としてお招きしたく存じます。
  Kana: らいげつのセミナーにこうしとしておまねきしたくぞんじます。
  Translation: We would like to invite you to serve as an instructor at next month's seminar.
  Korean: 다음 달 세미나에 강사로 초청하고자 합니다.
  Romanization: da-eum dal se-mi-na-e gang-sa-ro cho-cheong-ha-go-ja ham-ni-da.
  Both the Japanese 「お招きしたく存じます」 and the Korean 「초청하고자 합니다」 convey an organizer's intention to extend a formal invitation. The Korean 「초청하다」 is commonly used when inviting external speakers or experts, making its typical context quite similar to that of formal invitations in Japanese.
• Example: 記念式典に皆様をお招きしたく存じます。
  Kana: きねんしきてんにみなさまをおまねきしたくぞんじます。
  Translation: We would be honored to welcome you all to the commemorative ceremony.
  Korean: 기념식에 여러분을 모시고자 합니다.
  Romanization: gi-nyeom-si-ge yeo-reo-bu-neul mo-si-go-ja ham-ni-da.
  Japanese uses 「お招きしたく存じます」 to convey a respectful invitation, while Korean uses 「모시고자 합니다」 to emphasize respect for the invitees. Both sentences are well suited to ceremonial invitations, but they would sound overly formal for an ordinary dinner with friends.

◆ Differences from Korean 「초대합니다／모시고자 합니다」:

In ordinary invitation contexts, the Japanese 「ご招待します」 and the Korean 「초대합니다」 are quite similar. Both can directly communicate an invitation to an event. However, Japanese can adjust the degree of respect and humility through expressions such as 「ご招待いたします」 and 「お招きしたく存じます」. Korean can instead select among verbs such as 「초대하다」「초청하다」 and 「모시다」, then combine them with appropriate formal endings.

The Korean 「초청하다」 also does not necessarily have to be translated into Japanese as 「招請する」. When inviting a speaker, Japanese expressions such as 「お招きする」 or 「ご講演をお願いする」 often better communicate the actual purpose. Therefore, when comparing Korean and Japanese, first determine whether the context involves a general invitation, a request for a speaking engagement, or an invitation to a distinguished guest. Then choose the most natural sentence.

Understanding Korean 「참석해 주시겠습니까?／참석해 주시면 감사하겠습니다」 and Japanese 「ご出席いただけますか／ご出席いただけますと幸いです」

The Japanese 「ご出席いただけますか」 and the Korean 「참석해 주시겠습니까?」 are both used to ask whether someone is willing to attend an event. They are suitable for business invitations, seminars, and formal meetings. For a more indirect invitation, Japanese can use 「ご出席いただけますと幸いです」, while Korean can use 「참석해 주시면 감사하겠습니다」.

The difference between these pairs of expressions lies in their sentence functions. The first pair directly asks about the person's willingness to attend in a formal manner. The second pair uses a conditional construction to politely express the hope that the person will participate. This distinction exists in both Japanese and Korean, so not every invitation sentence should be understood simply as "Please attend."

◆ Similar Expressions: 「ご出席いただけますか／ご出席いただけますと幸いです」

The Japanese 「ご出席いただけますか」 uses the potential form of 「いただく」 to ask whether someone is willing to attend. The Korean 「참석해 주시겠습니까?」 asks about willingness through an honorific form of 「주다」 and a formal question ending. Although their grammatical structures differ, their functions in formal invitations are similar.

Both 「ご出席いただけますと幸いです」 and 「참석해 주시면 감사하겠습니다」 use conditional constructions that make an invitation sound more indirect. However, these sentences mainly express the hope that the recipient will attend. If a reply is needed by a specified date, that requirement should be stated separately.

• Example: 来週のセミナーにご出席いただけますか。
  Kana: らいしゅうのセミナーにごしゅっせきいただけますか。
  Translation: Would you be willing to attend next week's seminar?
  Korean: 다음 주 세미나에 참석해 주시겠습니까?
  Romanization: da-eum ju se-mi-na-e cham-seo-kae ju-si-get-seum-ni-kka?
  Both the Japanese 「ご出席いただけますか」 and the Korean 「참석해 주시겠습니까?」 directly ask about the recipient's willingness to attend. Japanese uses the humble verb 「いただく」, while Korean uses 「-시-」 to show respect toward the invitee. Both are appropriate for formal business invitations.
• Example: ご出席いただけますと幸いです。
  Kana: ごしゅっせきいただけますとさいわいです。
  Translation: We would be very grateful if you could attend.
  Korean: 참석해 주시면 감사하겠습니다.
  Romanization: cham-seo-kae ju-si-myeon gam-sa-ha-get-seum-ni-da.
  The Japanese 「幸いです」 conveys that the inviting party would be grateful if the recipient could attend. Korean expresses gratitude more directly with 「감사하겠습니다」. Both sentences are common in formal invitations and do not directly require the recipient to accept.
• Example: 出欠を金曜日までにお知らせいただけますと幸いです。
  Kana: しゅっけつをきんようびまでにおしらせいただけますとさいわいです。
  Translation: We would greatly appreciate it if you could let us know by Friday whether you will attend.
  Korean: 참석 여부를 금요일까지 알려 주시면 감사하겠습니다.
  Romanization: cham-seok yeo-bu-reul geu-myo-il-kka-ji al-lyeo ju-si-myeon gam-sa-ha-get-seum-ni-da.
  Both the Japanese 「出欠をお知らせいただけますと幸いです」 and the Korean 「참석 여부를 알려 주시면 감사하겠습니다」 ask the recipient to confirm attendance. The emphasis has shifted from inviting someone to confirming the number of attendees, so both expressions need a clearly specified reply deadline.

◆ Differences from Korean 「참석해 주시겠습니까?／참석해 주시면 감사하겠습니다」:

The Japanese 「ご出席いただけますか」 and the Korean 「참석해 주시겠습니까?」 both ask directly about willingness, but they construct honorific language differently. Japanese uses 「ご出席いただく」 to express receiving a benefit from the other person's action. Korean uses 「참석해 주시다」 to express the other person attending on behalf of the inviting party, while also showing respect through 「-시-」.

There is also no need to translate the Japanese 「ご出席いただけますと幸いです」 word for word into Korean using a term for "luck" or "happiness." In formal Korean invitations, 「참석해 주시면 감사하겠습니다」 is the more natural equivalent. When organizers need to confirm the number of attendees, both languages should include a reply deadline rather than relying solely on a polite invitation sentence.

Understanding Korean 「함께하실래요?」 and Japanese 「ご一緒しませんか」

Both the Japanese 「ご一緒しませんか」 and the Korean 「함께하실래요?」 can be used to invite someone to participate in an activity together. They are suitable for familiar colleagues, people with whom you regularly interact at work, or others who deserve courtesy without requiring the tone of an official document.

Both expressions ask about the recipient's willingness, but the Japanese 「ご一緒しませんか」 extends the invitation through a negative question, whereas the Korean 「함께하실래요?」 uses 「-(으)ㄹ래요?」 to ask whether the person would like to join. Their conversational functions are similar, but their grammatical structures differ.

◆ Similar Expression: 「ご一緒しませんか」

The Japanese 「ご一緒しませんか」 is a natural, polite way to invite someone. It can be combined with expressions such as 「よろしければ」 or 「ご都合がよろしければ」 to check whether the person is available first. In Korean, you can use 「함께하실래요?」 or 「같이 식사하실래요?」, adding 「시간 괜찮으시면」 at the beginning to leave the recipient room to decide.

These sentences are suitable for ordinary dinners or invitations among colleagues. However, a formal invitation to an external professor to speak at a seminar will generally require more explicit business invitation language.

• Example: 明日の夕食会、ご都合がよろしければご一緒しませんか。
  Kana: あしたのゆうしょくかい、ごつごうがよろしければごいっしょしませんか。
  Translation: Would you like to join us for tomorrow's dinner if you're available?
  Korean: 내일 저녁 모임이 있는데, 시간 괜찮으시면 함께하실래요?
  Romanization: nae-il jeo-nyeong mo-i-mi in-neun-de, si-gan gwaen-cha-neu-si-myeon ham-kke-ha-sil-lae-yo?
  Japanese uses 「ご都合がよろしければ」 to check the recipient's availability first, while Korean uses 「시간 괜찮으시면」 to express a similar meaning. Both are polite and suitable for inviting familiar colleagues to a gathering.
• Example: 金曜日、よかったら一緒に食事しませんか。
  Kana: きんようび、よかったらいっしょにしょくじしませんか。
  Translation: If you're free on Friday, would you like to have a meal together?
  Korean: 금요일에 시간 괜찮으시면 같이 식사하실래요?
  Romanization: geu-myo-i-re si-gan gwaen-cha-neu-si-myeon ga-chi sik-sa-ha-sil-lae-yo?
  The Japanese 「よかったら」 is appropriate for polite everyday invitations, and the Korean 「시간 괜찮으시면」 also sounds natural. There is no need to use 「초청합니다」 in Korean because the two people are discussing an ordinary meal, not formally inviting an external guest.
• Example: ご都合が悪ければ、またの機会にしましょう。
  Kana: ごつごうがわるければ、またのきかいにしましょう。
  Translation: If the timing isn't convenient, let's leave it for another time.
  Korean: 시간이 안 되시면 다음에 함께해요.
  Romanization: si-ga-ni an doe-si-myeon da-eu-me ham-kke-hae-yo.
  Both the Japanese 「またの機会にしましょう」 and the Korean 「다음에 함께해요」 let the recipient know that there is no need to force themselves to attend. "Next time" here merely suggests another possible opportunity and does not promise a specific date.

◆ Differences from Korean 「함께하실래요?」:

The Japanese 「ご一緒しませんか」 and the Korean 「함께하실래요?」 can both invite someone to join an activity. However, Japanese uses a negative question, while Korean directly asks about willingness through 「-(으)ㄹ래요?」. Both can naturally be understood as "Would you like to join us?" There is no need to force the Japanese negative construction into the Korean equivalent.

One point to note is that although 「함께하실래요?」 contains honorific language, it is still relatively conversational. When contacting an important client for the first time, inviting an external speaker, or addressing a guest at a formal ceremony, expressions such as 「참석해 주시겠습니까?」 or 「초청하고자 합니다」 are generally more appropriate. Japanese makes similar distinctions based on context. 「ご一緒しませんか」 works among familiar colleagues, but formal invitations generally use more ceremonious wording.

Understanding Korean 「참석이 어렵습니다／참석하지 못할 것 같습니다」 and Japanese 「出席が難しいです／出席できそうにありません」

The Japanese 「出席が難しいです」 and the Korean 「참석이 어렵습니다」 can both be used to politely decline an invitation, indicating that attendance is not possible because of scheduling or other circumstances. 「出席できそうにありません」 and 「참석하지 못할 것 같습니다」 have a nuance similar to "I'm afraid I won't be able to attend" and are more indirect than simply saying 「出席できません」 or 「참석하지 못합니다」.

Both languages can soften the directness of a refusal by using expressions that suggest difficulty or an inability to attend. However, if you already know you cannot participate, it is best to make your decision clear in the surrounding context. Otherwise, the recipient may interpret the indirect wording as a sign that further discussion is possible.

◆ Similar Expressions: 「出席が難しいです／出席できそうにありません」

The Japanese 「出席が難しいです」 literally means that attendance is difficult and can be used to politely decline in a formal reply. The Korean 「참석이 어렵습니다」 is used similarly, making the two expressions easy to match in responses to business events, seminars, or formal gatherings.

「出席できそうにありません」 and 「참석하지 못할 것 같습니다」 are closer to "I'm afraid I won't be able to attend." Japanese uses 「できそうにない」 to indicate that participation appears difficult under the current circumstances, while Korean uses 「-ㄹ 것 같습니다」 to soften the wording. Both can be used when the speaker has already decided to decline and do not necessarily mean that the decision is still pending.

• Example: あいにく予定が重なっており、今回は出席が難しいです。
  Kana: あいにくよていがかさなっており、こんかいはしゅっせきがむずかしいです。
  Translation: Unfortunately, I am unable to attend this time because of a scheduling conflict.
  Korean: 아쉽게도 일정이 겹쳐 이번에는 참석이 어렵습니다.
  Romanization: a-swip-ge-do il-jeong-i gyeop-chyeo i-beo-ne-neun cham-seo-gi eo-ryeop-seum-ni-da.
  Both the Japanese 「出席が難しいです」 and the Korean 「참석이 어렵습니다」 politely decline by describing attendance as difficult. Because the scheduling conflict has already been explained, both sentences will generally be understood as clear refusals.
• Example: 申し訳ありませんが、その日は出席できそうにありません。
  Kana: もうしわけありませんが、そのひはしゅっせきできそうにありません。
  Translation: I'm sorry, but I'm afraid I won't be able to attend that day.
  Korean: 죄송하지만 그날은 참석하지 못할 것 같습니다.
  Romanization: joe-song-ha-ji-man geu-na-reun cham-seo-ka-ji mo-tal geot gat-seum-ni-da.
  Both the Japanese 「出席できそうにありません」 and the Korean 「참석하지 못할 것 같습니다」 make the refusal sound softer. They are suitable when you do not want your reply to seem too blunt. However, if the organizer needs a confirmed headcount, you should still make clear whether your inability to attend is definite.
• Example: 私用のため、今回の会議には出席できません。
  Kana: しようのため、こんかいのかいぎにはしゅっせきできません。
  Translation: I am unable to attend this meeting due to personal circumstances.
  Korean: 개인적인 사정으로 이번 회의에는 참석할 수 없습니다.
  Romanization: gae-in-jeo-gin sa-jeong-eu-ro i-beon hoe-ui-e-neun cham-seo-kal su eop-seum-ni-da.
  Both the Japanese 「出席できません」 and the Korean 「참석할 수 없습니다」 directly state an inability to attend. Their meaning is clearer than 「難しいです」 or 「어렵습니다」, but that does not necessarily make them impolite. Combined with an appropriate reason and courteous wording, they can be used naturally in formal replies.

◆ Differences from Korean 「참석이 어렵습니다／참석하지 못할 것 같습니다」:

The Japanese 「出席が難しいです」 and the Korean 「참석이 어렵습니다」 serve very similar functions when politely declining invitations. Both avoid using a direct word for "refuse." However, Japanese may use expressions such as 「出席が難しい状況です」 or 「参加が難しくなりました」 depending on the occasion, while Korean commonly uses 「참석이 어렵습니다」 or 「참석하기 어렵습니다」. The Japanese 「難しい」 should not always be mapped to one fixed Korean grammatical structure.

Furthermore, both the Japanese 「出席できそうにありません」 and the Korean 「참석하지 못할 것 같습니다」 have an indirect tone, but that does not necessarily mean attendance is still possible. If the decision not to attend has already been made, speakers of either language can express gratitude for the invitation first, then give a brief reason so the organizer understands that the response is a definite refusal.

Understanding Korean 「초대해 주셔서 감사합니다／사양하겠습니다」 and Japanese 「お招きいただきありがとうございます／辞退いたします」

The Japanese 「お招きいただきありがとうございます」 and the Korean 「초대해 주셔서 감사합니다」 both express gratitude for an invitation and work well at the beginning of a polite refusal. If you have already decided not to accept the invitation, Japanese can use 「辞退いたします」, while Korean can use 「사양하겠습니다」 to communicate a formal decision to decline.

However, 「辞退いたします」 and 「사양하겠습니다」 are not interchangeable in every situation. The Japanese verb 「辞退する」 is commonly used when declining invitations, positions, proposals, or other opportunities. The Korean 「사양하다」 carries the nuance of courteously declining someone's kindness or offer. If you simply cannot attend because of a scheduling conflict, 「참석이 어렵습니다」 will generally sound more natural than 「사양하겠습니다」 in an ordinary Korean event reply.

◆ Similar Expressions: 「お招きいただきありがとうございます／辞退いたします」

The Japanese 「お招きいただきありがとうございます」 uses the humble verb 「いただく」 to express gratitude for being invited. The Korean 「초대해 주셔서 감사합니다」 uses the 「-아/어 주시다」 construction to convey respect and gratitude toward the person extending the invitation. Both are common expressions, but the Japanese and Korean honorific structures do not correspond word for word.

When formally declining, Japanese can use 「辞退いたします」 or 「遠慮させていただきます」, while Korean offers 「사양하겠습니다」. However, using such formal refusal expressions for an ordinary dinner or private invitation may sound excessively ceremonious. In both languages, the wording should be adjusted to the relationship between the people involved.

• Example: このたびはお招きいただき、ありがとうございます。
  Kana: このたびはおまねきいただき、ありがとうございます。
  Translation: Thank you very much for this invitation.
  Korean: 이번에 초대해 주셔서 감사합니다.
  Romanization: i-beo-ne cho-dae-hae ju-syeo-seo gam-sa-ham-ni-da.
  Both the Japanese 「お招きいただき」 and the Korean 「초대해 주셔서」 express gratitude for being invited. These expressions can be used on their own to thank someone or placed at the beginning of a polite refusal before explaining why attendance is not possible.
• Example: 大変恐縮ですが、今回は辞退いたします。
  Kana: たいへんきょうしゅくですが、こんかいはじたいいたします。
  Translation: I'm very sorry, but I must respectfully decline this time.
  Korean: 죄송하지만 이번에는 정중히 사양하겠습니다.
  Romanization: joe-song-ha-ji-man i-beo-ne-neun jeong-jung-hi sa-yang-ha-get-seum-ni-da.
  Both the Japanese 「辞退いたします」 and the Korean 「사양하겠습니다」 clearly express a refusal. They are suitable for formally declining invitations or proposals, but such ceremonious wording is generally unnecessary when you are simply unable to attend an ordinary event.
• Example: せっかくお招きいただいたのですが、今回は出席を遠慮させていただきます。
  Kana: せっかくおまねきいただいたのですが、こんかいはしゅっせきをえんりょさせていただきます。
  Translation: I appreciate your thoughtful invitation, but I must respectfully decline and will not be attending this time.
  Korean: 초대해 주셔서 감사하지만 이번에는 참석을 사양하겠습니다.
  Romanization: cho-dae-hae ju-syeo-seo gam-sa-ha-ji-man i-beo-ne-neun cham-seo-geul sa-yang-ha-get-seum-ni-da.
  Both the Japanese 「遠慮させていただきます」 and the Korean 「사양하겠습니다」 can be used to decline politely. However, the Japanese 「遠慮する」 can also mean exercising restraint or avoiding imposing on someone, in addition to declining an offer. The Korean 「사양하다」 more directly indicates that the speaker will not accept an invitation or another person's kindness. The two expressions therefore correspond only in contexts that actually involve a refusal.

◆ Differences from Korean 「초대해 주셔서 감사합니다／사양하겠습니다」:

The Japanese 「お招きいただきありがとうございます」 and the Korean 「초대해 주셔서 감사합니다」 are both appropriate opening expressions when responding to an invitation. In either language, an explanation that attendance is not possible can follow. The main difference lies in the honorific structure: Japanese uses 「いただく」 to express receiving a benefit from the other person's action, while Korean uses 「주시다」 to show respect toward the person extending the invitation.

As for 「辞退いたします」 and 「사양하겠습니다」, both can express a formal refusal, but neither is necessary every time you decline an invitation. If the issue is simply a scheduling conflict, Japanese can use 「今回は出席が難しいです」, while Korean can use 「이번에는 참석이 어렵습니다」. Both clearly explain that participation is not possible without sounding unnecessarily harsh in an ordinary event reply. When comparing formal invitations and refusals in Korean and Japanese, the choice should be based on the sentence's actual intention, the speaker's position, and the relationship between the parties. There is no need to force every honorific element into an identical grammatical form.

The appropriate Korean expressions for formal invitations and polite refusals vary depending on the recipient and occasion. 「초대합니다」 works for general events, while more formal expressions such as 「초청하고자 합니다」 and 「모시고자 합니다」 are common when inviting speakers or distinguished guests. For familiar colleagues or friends, a question such as 「시간 괜찮으시면 함께하실래요?」 sounds more natural.

When you receive an invitation but cannot attend, it is enough to express gratitude first and then explain the situation using 「참석이 어렵습니다」 or 「참석하지 못할 것 같습니다」. If you do not wish to disclose the reason, there is no need to force an explanation. If you already know that you cannot attend, it is best to say so directly rather than leave the other person waiting. This is especially important for events requiring advance seating arrangements or a confirmed headcount, where a clear response is more appropriate than repeatedly saying that you will think about it.
