-기만 하다: Only Does… — Limiting the Action

Construction: nominal -기 + 만 + 하다 — does only that action (and little else).

Before this, make sure you know: 만 , -기 , -아요 / -어요

How to form it

When	Form	Example
Verb + -기만 하다	-기만 하다	먹기만 하다 / 놀기만 하다 / 듣기만 하다
With tense / endings	-기만 했어요 / -기만 한다	보기만 했어요 / 말하기만 한다

-기만 하다 means only does… / just keeps …-ing — the action is limited to that.

Why this is hard

It can sound like complaint: they only complain, they only play. Learners confuse it with soft ‘just’ politeness. Limitation (and often frustration) is the job.

What it does

You narrow the action to one thing — and often imply that is not enough.

울기만 해요.
말만 하기만 해요.
놀기만 했어요.
걱정만 하기만 하지 말고 해 봐요.

Forms

Verb + -기만 하다. Related N만 patterns exist; keep the -기만 하다 chunk clear.

When not to use it

Do not use it as a gentle softener like English ‘just’. Do not confuse it with -만 하다 ‘about the size of’. Do not use it when multiple actions are equally in focus.

Neighbours — and why they differ

Form	Why it is not this slot
뿐	Only / nothing but — different attachment.
-고 싶다	Want to — desire, not limitation.
-기가 쉽다	Prone to — tendency, not ‘only does’.

Complaint and disappointment ride along for free. Parents, teachers, and tired friends use it when one action crowds out everything else. Soft English “just” is a false friend — Korean -기만 하다 narrows and often judges.

Ask: am I saying they only do that (often with complaint)? If yes, -기만 하다. If you mean ‘prone to,’ use -기가 쉽다.

Do not confuse it with

만

only, just — and why it takes a positive verb where 밖에 takes a negative

밖에

nothing but — and why the verb after it must be negative

-을 만하다

worth doing / decent enough — worth the effort or acceptable

Common questions

Dictionary?

Educational build: -기 + particle 만 + 하다. Limits the action to that verb. Not the adjective 만하다 (-을 만하다).

Vs particle 만 alone?

만 can limit nouns (밥만). -기만 하다 limits the action itself (먹기만).

Vs -을 만하다?

Huge trap. 볼 만하다 ≈ worth seeing. 보기만 하다 ≈ only looks (doesn’t buy, etc.).

Complaint tone?

Often yes — 공부하기만 하고 운동은 안 해.
