The 100 Most Common Korean Words

Word frequency in Korean is steeply front-loaded. The hundred words below account for a large share of everything said in ordinary conversation, and almost every one of them appears in TOPIK level 1.

They are grouped by function rather than alphabetically, because related words hold each other in memory and an alphabetical list gives your brain nothing to grip.

What This List Deliberately Leaves Out

You will notice there are no particles here — no 은/는, 이/가, 을/를. That is intentional. Particles are not vocabulary, they are grammar, and they need to be understood rather than memorised. They are covered in the particles guide.

Also missing: 당신. It is in every phrasebook as “you” and Koreans almost never use it. In real speech you use the person's name plus a title (민수 씨), their role (선생님, 사장님), or you simply drop the subject entirely. Using 당신 with a stranger sounds confrontational.

How to Learn These Without Wasting the List

1. Verbs first, in dictionary form and 해요 form together. 먹다 alone is not usable; 먹어요 is. Learn both at once — the conjugation rules are in the 해요 form guide.
2. Learn the pronunciation, not the spelling. 학교 is hak-kkyo, 좋다 is jo-ta, 같이 is ga-chi. Learning these with the wrong sound means relearning them later. See Korean pronunciation rules.
3. Ten a day, with review. The list is ten days of work, not one afternoon. Words added faster than you can review them do not stay.
4. Learn each word inside a sentence. 좋다 and 좋아하다 both translate as “like/good” and behave completely differently. A word list will never tell you that; an example sentence will.
5. Note the –하다 pattern. 공부하다, 일하다, 말하다, 생각하다, 좋아하다 — a noun plus 하다 makes a verb. Once you see it, hundreds of verbs become predictable.

Frequently asked questions

How many Korean words do I need to know?

About 1,000 words covers basic conversation, 3,000 gets you through daily life comfortably, and 5,000 to 6,000 is enough for most television and news. The first hundred do a disproportionate amount of work because Korean word frequency is steeply front-loaded.

What are the most common Korean words?

The highest-frequency items are the core verbs 하다 to do, 있다 to exist, 없다 to not exist, 되다 to become, 가다 to go, 오다 to come and 보다 to see, along with the demonstratives 이것, 그것 and 저것 and the question words 누구, 뭐, 어디, 언제, 왜 and 어떻게.

Should I learn Korean words in dictionary form or conjugated?

Both, together. The dictionary form 먹다 cannot be used in a sentence as it stands, and the 해요 form 먹어요 is what you will actually say. Learning them as a pair from the start avoids a second pass later.

Why is 당신 not in this list?

Because Koreans rarely use it, despite every phrasebook translating it as you. In real speech you use the person's name with 씨, their title such as 선생님 or 사장님, or you drop the subject altogether. Using 당신 with a stranger can sound confrontational.

What is the –하다 pattern?

A very productive rule where a noun plus 하다 becomes a verb: 공부 study plus 하다 gives 공부하다 to study, and 일 work plus 하다 gives 일하다 to work. Recognising it turns hundreds of Korean verbs into predictable combinations rather than separate items to memorise.
