Different Ways to Say “Goodnight” in Korean

In English, people normally say “goodnight” or “sweet dreams” to someone to wish them a good night. On the other hand, in Korean, there are plenty of ways to express this phrase depending on who you are speaking with and when it happens. Let’s know more below!

Formal “Goodnight” in Korean

The first way is through its formal version. Below are ways to say “goodnight” when you are talking to someone older or someone of a higher social status than you.

If you have studied “How to Say Goodbye in Korean,” then you will be aware of the word 안녕히 (annyeonghi | peacefully) already.

The next word is the formal version of 자다 (jada | to sleep). Both of these are some of the most common Korean words, similar to what is on this list

In order to show respect in Korean, you not only need to add 시 into expressions, but you also need to change certain words. 

From the lesson on saying goodbye, we learned that 계세요 (gyeseyo) comes from the honorific version of 있다 (itda). Likewise, if you want to say “sleep” in a formal setting, then you should use the word 주무세요 (jumuseyo). Use the expression 안녕히 주무세요 (annyeonghi jumuseyo) when speaking to people who are your senior or who are a generation or two older than you.

Another expression you can use is 편안한 밤 되세요 (pyeonanhan bam doeseyo). This comes from the verb 편안하다 (pyeonanhada | to be comfortable) and the word 밤 (bam)which means “night” so the expression’s literal meaning is something like “have a comfortable night.”

What is “Sweet Dreams” in Korean?

Another phrase you often say when greeting someone goodnight is “sweet dreams.” Here’s how you can say it in Korean.

There are several Korean verbs that usually are made up of two separate words. 꿈을 꾸다 (kkumeul kkuda) is one of these, 꿈 (kkum) means dream so literally 꿈 꾸다 (kkum kkuda) could be translated as “dream dreams”, but you should see the two words together as an expression meaning “to dream”. 좋은 (joeun) means “good this expression means something like “dream some good dreams.”

Use these expressions with people who are of a similar age and rank, but you don’t know too well.

For this version, we just dropped the 요 (yo) if you will say this to someone you’re close with. 

“Did you sleep well?” in Korean

If you see somebody the next day and want to ask them if they slept soundly or they slept well, here’s what you can say.

 The verb 주무시다 (jumusida) has been put into the past tense and asked as a question forming 안녕히 주무셨어요? (annyeonghi jumusyeosseoyo).

You can use 잘 잤어요? (jal jasseoyo), which is the standard form of “good morning”, with your fellow housemates or if you’re traveling with someone who is older than you.

잘 잤어? (jal jasseo) is informal so you can use this with people the same age or close friends.

      I want to ask a question about 좋은 꿈 꿔 and 좋은 꿈 꿔요. You said we can say 좋은 꿈 꿔 to somebody who we are close to and 좋은 꿈 꿔요 to somebody we are not close to. So, the difference only with the word 요?
      Am I right?

      Thank you

        The main difference is when we add요 in the last of the word, it shows that we are using formal way of talking , which we can use to our elders to show respect.
