Kamsahamnida: How to Say Thank You in Korean

---

The most useful way to say “thank you” in Korean is 감사합니다 (gamsahamnida). It works in formal situations and is a good starting point when you do not yet know which speech style a relationship calls for.

Korean gratitude is not a ladder where one phrase maps mechanically to a person’s age or job title. Your relationship, the setting and the speech style you already use together all matter. This guide gives you a reliable first choice, then shows when 고맙습니다, 고마워요 and 고마워 fit.

If you are new to the language, start with the Korean learning guide, then practise these phrases as complete exchanges rather than isolated vocabulary.

In this video, Caitlin Sacasas models the main expressions. The Fi3M player and YouTube version are kept together so you can use whichever one loads for you.

Thank You in Korean: 감사합니다

감사합니다 (gamsahamnida) comes from 감사하다, “to appreciate” or “to be thankful”. 감사 is a Sino-Korean noun meaning “gratitude”, and 합니다 is a formal-polite ending.

Use 감사합니다 for a service interaction, a first meeting, a teacher, a colleague you address politely or a formal message. You can also use it with someone close when the moment itself is formal or you want a deliberately formal tone.

• 시간을 내 주셔서 감사합니다. (Sigan-eul nae jusyeoseo gamsahamnida.) “Thank you for making time.”
• 도와주셔서 감사합니다. (Dowajusyeoseo gamsahamnida.) “Thank you for helping me.”

The common romanisation gamsahamnida follows the spoken form: the ㅂ in 합니다 is pronounced as ㅁ before ㄴ. The National Institute of Korean Language’s romanisation system is based on standard Korean pronunciation, but romanisation is still only a cue. Listen to the video and compare your recording with Caitlin’s rather than relying on an English respelling. Learning to read Korean Hangul will make these sound changes easier to track.

Another Formal-Polite Thank You: 고맙습니다

고맙습니다 (gomapseumnida) comes from the native Korean adjective 고맙다, “to be grateful”. It uses the same formal-polite speech style as 감사합니다.

The National Institute of Korean Language says both expressions can be used when thanking someone for help or kindness. 고맙다 is native Korean, while 감사하다 contains the Sino-Korean word 감사; that difference does not make 고맙습니다 an automatically lower or less respectful form.

• 이해해 주셔서 고맙습니다. (Ihaehae jusyeoseo gomapseumnida.) “Thank you for understanding.”
• 와 주셔서 고맙습니다. (Wa jusyeoseo gomapseumnida.) “Thank you for coming.”

The Korean Learners’ Dictionary records the pronunciation of 고맙습니다 as [고맙씀니다]. That is another reason to treat gomapseumnida as a reading aid rather than a complete pronunciation lesson.

Everyday Polite Thanks: 고마워요

고마워요 (gomawoyo) is the everyday polite form of 고맙다. It belongs to the 해요체 (haeyoche) speech style: conversational rather than formal, but still polite.

You may hear it between colleagues, neighbours, acquaintances and family members who normally use polite speech together. It is not “too formal for friends and too informal for strangers”; the relationship and setting decide whether it sounds natural.

프로젝트를 도와주셔서 고마워요. (Peurojekteureul dowajusyeoseo gomawoyo.) means “Thank you for helping with the project.”

In 도와주셔서, 도와주다 means “to help” and 주시다 adds honorific respect for the person doing the helpful action. The ending -어서 gives the reason for the thanks; 주셔서 does not simply mean the English word “for”.

Casual Thanks: 고마워

고마워 (gomawo) is the casual form. Use it in a relationship where both people already use 반말 (banmal), such as with a close friend, partner, sibling or another person who has agreed to casual speech.

Being younger does not by itself give a stranger permission to use casual speech. If you are unsure, stay with a polite form until the relationship makes the choice clear.

• 도와줘서 고마워. (Dowajwoseo gomawo.) “Thanks for helping me.”
• 커피 가져다줘서 고마워! (Keopi gajyeodajwoseo gomawo!) “Thanks for bringing the coffee!”

Using a Bow or Nod When You Say Thanks

A small bow or nod often accompanies an in-person thank you, just as it can accompany a Korean greeting. There is no useful fixed angle to memorise for every person and situation.

In an ordinary shop or café exchange, a spoken thanks and small nod can be enough. Formal ceremonies and business settings can have their own protocol, so follow the people hosting the event rather than trying to calculate a bow from status alone.

How to Emphasise Gratitude Formally

Add an adverb when you want to strengthen a formal-polite thank you:

• 정말 감사합니다. (Jeongmal gamsahamnida.) “Thank you very much.”
• 진심으로 감사합니다. (Jinsimeuro gamsahamnida.) “Thank you sincerely.”
• 대단히 감사합니다. (Daedanhi gamsahamnida.) “Thank you very much.” This has a particularly formal or emphatic tone and is common in set announcements, speeches and formal writing.

The adverb does not create a new speech level. The ending still carries the formal-polite relationship.

How to Emphasise Casual or Everyday Thanks

The same idea works with everyday polite and casual forms:

• 정말 고마워요. (Jeongmal gomawoyo.) “Thank you so much.”
• 너무 고마워. (Neomu gomawo.) “Thanks so much.”
• 저녁 만들어 줘서 정말 고마워. (Jeonyeok mandeureo jwoseo jeongmal gomawo.) “Thanks so much for making dinner.”

Keep the ending consistent with the relationship. Adding 정말 or 너무 does not make a casual ending polite.

How to Respond to Thanks in Korean

Korean does not require one fixed equivalent of “you’re welcome”. Natural replies depend on what happened and the speech style:

• 아니에요. (Anieyo.) “Not at all.”
• 괜찮아요. (Gwaenchanayo.) “It’s okay.”
• 별말씀을요. (Byeolmalsseumeullyo.) “Don’t mention it.”
• 제가 더 감사하죠. (Jega deo gamsahajyo.) “I’m the one who should be thanking you.”

천만에요 (cheonmaneyo) appears in dictionaries and is understood, but it is not the only or automatic reply. In the National Institute of Korean Language’s 2022 usage survey, 아니에요 was the most frequent response to thanks, followed by several alternatives. Learn the exchange, not just a translation pair.

How to Say “No, Thank You” in Korean

For a polite refusal, 괜찮아요, 감사합니다 (Gwaenchanayo, gamsahamnida) means “I’m okay, thank you.” You can also say 아니요, 괜찮아요 (Aniyo, gwaenchanayo), “No, I’m okay.”

Notice the difference between 아니요, the polite “no” used to answer a question, and 아니에요, a form of 아니다 used in replies such as “It’s not [a problem]”. Context and tone matter, so add a brief reason when a bare refusal could sound abrupt.

Thanking Someone for Food in Korean

Before eating a meal that someone has prepared, provided or paid for, you may hear 잘 먹겠습니다 (jal meokgetseumnida). Literally it looks forward to eating well; in context, it acknowledges the meal and the person behind it.

After the meal, 잘 먹었습니다 (jal meogeotseumnida) means “I ate well” and functions as thanks for the meal. These are useful guest phrases, but meal etiquette varies by household and setting. Listen to your hosts instead of treating one age-based rule as universal.

Casual Korean Text Shorthand for Thanks

In very casual messages, you may see ㄱㅅ, an initial-consonant abbreviation of 감사. It is typed shorthand, not something to pronounce aloud.

감사 (gamsa) and 땡큐 (ttaengkyu, a Korean spelling of English “thank you”) can also sound playful or abbreviated. Keep them for close, casual contexts where that tone already fits. They are not replacements for a polite thank you to a stranger, teacher or client.

Practise Korean Thank-You Exchanges in Context

Start with four core choices:

• 감사합니다: formal-polite and a reliable first choice
• 고맙습니다: another formal-polite choice
• 고마워요: everyday polite
• 고마워: casual, for a relationship that already uses 반말

Now choose a short scene from a Korean drama or the video above. Note who is speaking, their relationship, the setting, the thank-you phrase and the reply. Shadow the whole exchange, record yourself, then role-play a similar situation with a tutor or proficient speaker. Ask which speech style they would choose and why, record the correction and use it in a new scenario a few days later.
