Korean KakaoTalk Messages: Words, Rules and Examples

What you will learn

• Read ten short chat messages and say what each shortened form stands for.
• Tell the reaction words ㅋㅋ, ㅎㅎ, ㅠㅠ and 넵 apart, and read the unread marker 1 and the status word 읽음.
• Choose a safe style for a friend, a colleague or a teacher.

Before you start: you should read Hangul blocks, as covered in how to read Hangul. Time: about 30 minutes. Audio plays only when you press a button.

Key Facts

• ㅋㅋ means laughter, ㅎㅎ is a softer laugh and ㅠㅠ shows crying or an apologetic face.
• Chat drops spaces, particles and sometimes the polite ending -요, so a message can look shorter than the sentence behind it.
• 넵 is a polite short yes used with seniors and colleagues, while 응 and ㅇㅇ are casual yes forms for close friends.
• In KakaoTalk, a small 1 beside a message means it is unread; the word 읽음 (read) is the status label in other apps.
• Consonant-only forms such as ㅇㅋ (오케이) and ㄱㅅ (감사) are chat-only shorthand, not standard spelling.

What Are Korean KakaoTalk Messages?

Korean KakaoTalk messages are the short texts people send on KakaoTalk (카카오톡, often shortened to 카톡), the chat app most people in Korea use for friends, family, work groups and shops. A message can be a full sentence, a single reaction such as ㅋㅋ, or a mix of both. The grammar is ordinary Korean, but the spelling, spacing and tone follow chat habits.

Three ideas explain almost everything you will see.

1. Chat is written speech. People type the way they talk, so particles drop, endings shorten and reactions stand alone.
2. Some forms are only chat. Letters such as ㅋㅋ and ㅇㅋ are not words in the dictionary. They are shorthand that friends understand.
3. The relationship sets the style. The same idea can be typed in casual 반말 to a friend and in polite 합니다 style to a teacher.

A group conversation is called a 단톡방 (dantokbang, group chat room). Any chat room is a 채팅방, and a one-to-one chat is often called 갠톡 (gaentok). In both, a small number 1 beside a message shows that it has not been read yet; the 1 disappears once it is read. Because chat spelling is not standard spelling, treat this lesson as reading help first and writing advice second.

Why Do English Speakers Struggle with Korean Chat?

English speakers struggle because chat Korean looks like a code made of letters they have only just learned. A learner who can read 낼 시간 돼? letter by letter still has to know that 낼 is short for 내일 and that the question is casual. English texting has its own shorthand (lol, omg, ty), but it spells out Latin letters. Korean chat uses the Hangul letters themselves, often without vowels, and the letter names are not the sounds.

The fix is a short routine: separate the reaction letters from the sentence, expand each shortened form, then decide the style. The next sections give you the forms to expand.

Which Reaction Words Do I Need?

You need about a dozen reaction words, and each one belongs to one of four types. In the table, Standard means normal dictionary Korean, Shortened means a real word cut short, Chat-only means symbols and letters with no dictionary entry, and Slang means casual words to recognise but use carefully.

Consonant-only shorthand takes the first consonant of each syllable. ㅇㅋ comes from 오케이 (OK), using the first consonants of 오 and 케, and ㄱㅅ is the first consonants of 감사 (gam-sa). Read them by thinking of the spoken word, not the letter names.

Two pairs deserve a closer look. 넵 (nep) and 응 (eung) both mean yes, but they are far apart in tone. 넵 is short and polite, so it suits a reply to a senior colleague. 응 is casual, so it suits a close friend. Neither can replace the other. A message to a teacher that says 응 sounds rude, and a message to a best friend that says 넵 may sound stiff or like a joke.

The status word 읽음 (ilgeum, read) and its opposite 안 읽음 (unread) appear in some messaging apps and notices. KakaoTalk shows the same idea with the number 1, which disappears once the message is read. The slang 읽씹 describes a person who read a message and did not reply, so you may see it in jokes about slow replies. Use it only as a reading item.

How Do Chat Endings Change?

Chat endings change with the relationship, and one message can appear in three styles. The idea behind the sentence stays the same: "I am going now."

Chat then adds its own habits on top of these styles.

• Dropped particles. 나 밥 먹었어 is understood without 는 and 을, just as in speech.
• Dropped spaces. 지금가요 is 지금 가요 typed fast. Split it into words before you read.
• Stretched endings. A tilde, as in 알겠어요~, makes the tone softer or more cheerful. A line of dots, as in 음..., shows hesitation.
• Playful endings. Some people type 안녕하세용 or 알겠어염 with a cute final sound. Recognise these as a friendly -요, and do not copy them until you know the person.
• Face marks. ^^ and ㅎㅎ are the usual way to soften a polite line.

Punctuation in chat is lighter than in writing. A question mark is kept, a full stop is usually left out, and repeated marks (!!) add energy. The informal punctuation page covers these marks in detail. For the grammar behind casual endings, see banmal. Next come the shortened words themselves.

How Do I Read Shortened Forms?

Read a shortened form by finding the full word it came from, because chat shortens a few common words in predictable ways. The ones below appear again and again.

Most of these drop a vowel or a final syllable and keep the first sounds. Some are so common that people use them in speech too, such as 근데 and 낼. Others are best kept for typing.

Here is a four-step reading method that works on any unknown message.

1. Split off the reaction letters. Take ㅋㅋ, ㅎㅎ and ㅠㅠ out first.
2. Add the spaces. Break the rest into words.
3. Expand the shortened words. Turn 낼 into 내일 and ㅇㅋ into 오케이.
4. Name the style. Look at the ending: -어/-아 is casual, -어요/-아요 is polite and -습니다 is formal.

You will know it worked when you can rewrite the message as a normal sentence. The next section gives you ten messages to practise on.

Five Sample Chats

Each chat below has two messages, so the five chats give you ten messages. Read the Korean first, cover the key, then check yourself.

Chat 1: two friends

A: 오늘 저녁에 뭐 해? ㅎㅎ B: 아무것도 안 해 ㅋㅋ 왜?

Key. 해 is casual 해요. ㅎㅎ is a soft, friendly laugh, and ㅋㅋ is a laugh. 아무것도 안 해 means "I am doing nothing", and 왜 means "why". Both lines are casual, so this chat is between close friends.

Chat 2: a student and a teacher

선생님: 내일 수업은 오후 세 시예요~ 학생: 넵! 감사합니다 ^^

Key. The teacher uses polite -예요 with a tilde for a gentle tone. The student answers 넵 (brisk polite yes), then the full 감사합니다 (thank you) and ^^ (a smile). The student keeps a polite style and does not use ㄱㅅ.

Chat 3: making a plan

A: 낼 시간 돼? B: ㅇㅇ 낼 봐!

Key. 낼 is short for 내일 (tomorrow). 시간 돼? is casual for "do you have time?". ㅇㅇ means 응응 (yes), and 낼 봐 is a casual "see you tomorrow".

Chat 4: running late

A: 도착했어요? B: 지금 가는 중이에요 ㅠㅠ 길이 막혀요

Key. 도착했어요 means "have you arrived?". 가는 중이에요 means "I am on my way", and ㅠㅠ shows an apologetic face. 길이 막혀요 means "the road is jammed", with the space and full stop missing.

Chat 5: a favour among friends

A: 이거 내가 보낼게 B: ㄱㅅ ㅎㅎ

Key. 보낼게 means "I will send it". ㄱㅅ stands for 감사 (thanks) and ㅎㅎ softens the reply. This pair is fine between friends and too casual for a boss.

Every key uses the same method: reaction letters out, spaces in, shortened words expanded, style named. Next, a decision you must make every time: how far to copy what you read.

Which Forms Should I Avoid in Formal Chats?

Avoid chat-only and casual forms in any message to a teacher, a boss, a client or a stranger, and use full polite sentences instead. A message that is correct but too casual can sound disrespectful, while a message that is a little too polite never causes trouble.

Workplaces differ. Some offices are relaxed and use 넵 and ㅎㅎ all day, while others expect complete sentences. When you are unsure, copy the style of the person who wrote to you first, and stay one step more polite.

One more rule: if you cannot say what a shorthand stands for, do not send it. Some consonant-only forms stand for rude words, and a learner who copies one without knowing it can offend. Now one form is worked through step by step.

Worked Example: ㅋㅋ

The laugh letters ㅋㅋ are the most common chat form, and one message shows how to read them.

그 영상 진짜 웃겨요 ㅋㅋ

1. Split off the reaction. The line is 그 영상 진짜 웃겨요 plus ㅋㅋ.
2. Read the sentence. 그 영상 means "that video", 진짜 means "really", and 웃겨요 is the polite form of 웃기다 (to be funny). Together: "That video is really funny."

3. Hear the sentence. 웃겨요 is spoken [욷껴요]: the final ㅅ sounds like ㄷ, and the ㄱ after it is tense. The clip says the sentence only, because ㅋㅋ is typed, not voiced.
4. Read the laugh. ㅋㅋ repeats the idea of the sentence as a laugh. One or two letters is a small laugh, and a long string such as ㅋㅋㅋㅋㅋ is a big one.
5. Name the style. 웃겨요 is polite and ㅋㅋ is friendly, so the message suits a friend or a younger colleague.
6. Reply. A natural answer is 맞아요 ㅋㅋ ("that's right"), or 저도요 ㅎㅎ ("me too").

You will know it worked when you can say what the message means and who it suits. The same six steps work for ㅎㅎ and ㅠㅠ. A few mistakes catch learners out.

What Mistakes Do Learners Make with Korean Chat?

The most common mistakes are copying casual forms to the wrong person, treating the letters as words and trusting chat spelling.

• Learners often assume ㅋㅋ is read like a word. Actually it is typed laughter, so read it as a laugh, not "kk", because it has no dictionary meaning.
• Learners often assume 넵 is very formal. Actually it is polite but brisk, so for a formal message use 네 or 알겠습니다, because 넵 can sound curt to some readers.
• Learners often assume ㅎㅎ and ㅋㅋ are the same. Actually ㅎㅎ is softer and fits more relationships, because ㅋㅋ is a louder, more casual laugh.
• Learners often assume chat spelling is correct spelling. Actually forms such as 낼 and 넘 are for typing, so write 내일 and 너무 in tests and formal messages, because standard spelling is expected there.
• Learners often assume that any shorthand is safe to copy. Actually some shorthand stands for rude words, so copy only what you can expand, because a wrong guess can offend.
• Learners often assume a reply of ㅇㅇ is polite enough. Actually ㅇㅇ is casual, so use 네 with seniors, because it carries the right respect.

These slips are easy to fix once you ask one question: who is reading this? Test yourself next.

Practice and Answer Key

Answer each question, then check the key.

1. What does ㅇㅋ stand for?
2. Which is the polite short yes: 넵, ㅇㅇ or 응?
3. What is the full form of 낼?
4. What is the full form of 담에?
5. What does 읽음 mean?
6. You are thanking your teacher. Which is safer: ㄱㅅ or 감사합니다?
7. What does ㅠㅠ show?
8. Add the space to 지금가요.
9. A friend ends a line with ㅎㅎ. What is the mood?
10. What does ㄱㅅ stand for?

Answer key:

1. 오케이 (OK).
2. 넵.
3. 내일 (tomorrow).
4. 다음에 (next time).
5. Read, meaning the other person has opened the message. In KakaoTalk, the same thing is shown by the 1 disappearing.
6. 감사합니다, because ㄱㅅ is too casual for a teacher.
7. Crying, sadness or an apologetic face.
8. 지금 가요 ("I am going now").
9. A soft, friendly laugh.
10. 감사 (thanks).

For a speaking task, say the spoken form of each shorthand aloud: 오케이, 감사, 응응. Then play each model clip and compare.

Where to Go Next

This lesson covers reaction letters, the most common shortened words, ending levels and ten sample messages. It does not cover emoji, stickers, voice messages or the many short-lived slang words that change year to year, and the sample chats are typical examples, not messages from real people. Chat habits also vary by age group and by workplace.

Next: Korean price tags and receipts, which reads the numbers and words on a shop receipt. For the phrases you can say and type, see Korean texting phrases. To return to the other lessons, see Real-World Texts (Signs, Menus).

Frequently Asked Questions

What does ㅋㅋ mean in Korean? ㅋㅋ means laughter, like "haha" or "lol" in English. It comes from the sound of a laugh, and the more ㅋ letters there are, the bigger the laugh. It is typed, not usually said aloud. Use it with friends and peers, and leave it out of messages to teachers, bosses and strangers.

How do Koreans text? Koreans mostly use KakaoTalk (카카오톡, or 카톡 for short). Messages are short and informal: spaces and particles are often dropped, reaction letters such as ㅋㅋ and ㅎㅎ are added, and the ending changes with the relationship. Close friends use casual 반말, while teachers and colleagues get polite -요 or -습니다 sentences.

Is chat Korean different from textbook Korean? Yes. Chat uses shortened words (낼 for 내일), consonant-only forms (ㅇㅋ), loose spacing and playful endings that textbooks do not teach. The grammar underneath is the same, so you can expand any chat line back into a normal sentence. In tests and formal messages, write the standard spelling.

What does 읽음 mean? 읽음 means "read", the noun form of 읽다 (to read). KakaoTalk itself shows read status with a small number 1 beside a message; the 1 means it is still unread, and it disappears once the other person opens it. The word 읽음, and its opposite 안 읽음 (unread), appear as status labels in other apps and in notices. Slang such as 읽씹 describes someone who read a message and did not answer.

Can I use ㅋㅋ or ㅇㅇ with my teacher? No, avoid both. ㅋㅋ and ㅇㅇ belong to chat between friends. To a teacher, boss or client, write a full polite sentence such as 알겠습니다. 감사합니다. If you want a softer tone, a short ^^ or ㅎㅎ is the most you should try, and only if the relationship is already friendly.
