How Do You Say Good Job in Korean?

The everyday way to say good job in Korean is 잘했어요. It comes from 잘하다 (jalhada, "to do well"), made of 잘 ("well") and 하다 ("to do"). The past tense 잘했어요 says "you did it well", so it praises a finished action and not a person's character.

Building the polite form takes three steps:

1. Take the verb 잘하다 and remove 다: 잘하-.
2. Change 하 to 해 and add the past marker ㅆ: 잘했-.
3. Add 어요: 잘했어요.

The present form 잘해요 means "you are good at it" and describes a skill, while 잘했어요 praises what just happened. The next section sets the forms out by listener.

What Are the Polite and Casual Ways to Say Good Job?

The right form depends on who is listening. The guide to Korean speech levels explains the system. In short: the word 잘했어요 flows downward or sideways, so use it with equals and juniors, and choose a different line for elders.

Polite: 잘했어요 (jalhaesseoyo)

잘했어요 is the standard praise. A teacher says it to a student, a parent to a child, and a coworker to an equal. Add 정말 (jeongmal, "really") or 아주 ("very") to raise the strength.

Casual: 잘했어 (jalhaesseo)

잘했어 drops the 요 and is for friends, siblings and children. A cheerful tone and the word 우와 make it warm. Play

Polite: 대단해요 (daedanhaeyo)

대단해요 means "impressive" and admires skill or effort, not just one result. It is safer than 잘했어요 across ages, because it does not grade the listener. For an elder, add the honorific -시- and say 대단하세요. Play

Polite: 수고했어요 (sugohaesseoyo)

수고했어요 thanks someone for effort and is common at the end of a task or a work day. It sounds like praise from a person of higher or equal rank. To a senior, use the formal 수고하셨습니다, which is a staple in Korean offices. Play Play

Pronunciation comes next, because the spelling hides a sound change.

How Do You Pronounce 잘했어요?

잘했어요 is pronounced [잘해써요], jalhaesseoyo in Revised Romanization, in four even syllables: jal-hae-sseo-yo. The first syllable ends in a clear ㄹ, and the tense ㅆ moves to the start of the third syllable.

1. 잘 (jal): a soft "ja" ending in an "l" sound.
2. 해 (hae): "heh".
3. 써 (sseo): a tense s, said with a firm tongue and no puff of air.
4. 요 (yo): short and level.

Sound Changes to Listen For

The spelling and the sound differ in two places, following the National Institute of Korean Language Standard Pronunciation rules (표준 발음법):

• 했어요 is [해써요]. The ㅆ at the end of 했 moves into the empty first slot of 어, and it keeps its tense sound. This is liaison, and the page on Korean tensification explains how tense sounds behave.
• 수고했어요 is [수고해써요]. The same move happens in the middle of the word.
• 수고하셨습니다 is [수고하셛씀니다]. The ㅆ of 셨 is read as [ㄷ] before a consonant, the ㅅ of 습 turns tense, and the ㅂ becomes [ㅁ] before ㄴ.

Revised Romanization writes 잘했어요 as jalhaesseoyo, matching the sound. With the sounds in place, the next question is when each form fits.

When Should You Use 잘했어요, and When Should You Not?

Use 잘했어요 to praise a result when you are equal to or senior to the listener, and avoid it when you are praising a boss or an elder. The lists below show where it fits and where it does not.

Situations Where It Fits

• A teacher praising a student. 잘했어요 is the classic school phrase.
• A parent or older sibling praising a child. 잘했어 and 참 잘했어요 are both natural.
• A friend after good news. 잘했어! shows that you are pleased.
• A coworker after a task. 수고했어요 thanks for the effort, and 잘했어요 praises the result.

Situations to Avoid

• A boss or an elder. 잘했어요 sounds like grading them. Use 대단하세요 (you are impressive) or 훌륭하세요 (you are excellent).
• A stranger. Praise from someone with no relationship can sound patronising. Use 대단하네요 or stay with a thank-you.
• A mistake. Said flatly after an error, 잘했어요 can sound sarcastic, as in "nice going". Tone decides the meaning.
• A skill compliment to an elder. Say 잘하시네요 (jalhasineyo, "you are good at it"), which adds -시- for respect.

Which Line Fits Which Listener

One table sorts the three kinds of praise by listener. Use it when you cannot decide in the moment.

Notice that the last row never uses 잘했어요. The grid is a guide, not a law: tone, closeness and workplace habits move the line, so watch what the people around you say. The dialogues below show these rules in everyday settings.

What Does Good Job Sound Like in a Real Conversation?

A Korean praise line is short and often followed by thanks. Listen for the polite ending in the first and third dialogues and the casual ending in the second.

What to notice: the teacher says 잘했어요, and the student answers with 감사합니다. 떨렸어요 means "I was nervous", from 떨리다.

What to notice: friends use 잘했어 and drop the 요. 덕분이야 (deokbuniya) means "it is thanks to you".

What to notice: the manager uses both 잘했어요 for the result and 수고했어요 for the effort. The junior answers with 수고하셨습니다 and the title 부장님 (bujangnim), because 수고했어요 would sound too casual upward. The same rank rules shape good work today in Korean.

What Should You Know about the Culture behind Good Job?

In Korean workplaces and schools, praise follows rank. A senior praises the result, and a junior thanks the senior for effort or compliments skill in respectful words.

• 수고하셨습니다 is a daily ritual. Colleagues say it at the end of the day or after a task, and it works like "thank you for your work".
• The school stamp. Teachers give young children a stamp that reads 참 잘했어요 ("very well done"), so the phrase carries a gentle, childlike tone for many adults.
• Praise often comes with a small push. After 잘했어요, people may add 다음에도 잘할 수 있어요 ("you can do well next time too") or 파이팅. See you can do it in Korean.
• 수고 to a superior is debated. The National Institute of Korean Language's etiquette guide (표준 언어 예절) advises against 수고 phrases toward a superior, because they sound like a judgement from above. In many offices 수고하셨습니다 is still said upward every day; if you want the safest line for a boss, say 감사합니다 or 고생 많으셨습니다.
• Humility is the standard reply. People answer with 감사합니다 or 아니에요, 아직 부족해요 ("no, I still lack skill").

An expert insight: learners often use 잘했어요 as a polite thanks to everyone, because it ends in 요. Korean sorts praise by relationship, so the 요 does not make it safe for a boss. The mistakes below follow from that.

What Mistakes Do Learners Make with Good Job in Korean?

Most mistakes come from praising upward or from confusing praise for a result with praise for a skill. The table collects the five most common ones.

Learners often assume that 수고했어요 is the best translation of "good job". Actually 수고했어요 means "you worked hard", which fits the end of effort, while 잘했어요 judges the quality of the result. In daily life, Koreans use them together, one for the effort and one for the result.

How Do You Reply When Someone Praises You in Korean?

Reply with a short thanks and a modest remark, because Korean etiquette values humility. The table gives replies by relationship.

Learners often hear 한국어 잘하시네요 ("you speak Korean well") from Koreans who are surprised and pleased. The verb 잘하다 appears again, with -시- for respect. A good reply is 아니에요, 아직 멀었어요 ("no, I still have a long way to go") or simply 감사합니다. The modest answer is polite, and accepting the compliment with thanks is also fine.

Is It the Same as Great Job or Nice Work?
