도 in Korean: “also, too, even”

도 (do) means "also" or "too" and attaches right after a noun: 저도 means "me too." With a negative verb it can also mean "even" or "not even." It is one of the first particles learners meet, and you will hear it constantly.

How to form it

How to use it

도 adds something to what was already said: "this one too." 저도 좋아해요 means "I like it too." It takes the place of 은/는, 이/가 and 을/를, so you never stack them together.

With 에, 에서 or 한테, 도 goes after the other particle: 주말에도 (on weekends too), 친구한테도 (to my friend too).

With a negative, 도 often means "not even": 물도 안 마셨어요 (I didn't even drink water). This adds a sense of surprise or emphasis.

도 itself has no politeness level, so it works in casual and polite speech alike. 나도 is casual "me too," 저도 is the polite version.

Don’t mix it up with

만: 만 means "only" and limits things, while 도 means "also" and adds things. 커피만 마셔요 is "I only drink coffee," 커피도 마셔요 is "I drink coffee too."

조차: 조차 also means "even," but it is stronger and mostly used for bad or disappointing situations. 도 is the everyday choice.

Common mistakes

Stacking 도 with 는 or 를, as in 저는도 or 커피를도. 도 replaces those particles: 저도, 커피도.
