-는 둥 마는 둥

-는 둥 마는 둥: Half-Doing It — Barely, Half-Heartedly

Bound noun 둥 「004」: seems to do it and not to — half-hearted / incomplete action (-은/는/을 둥 만/마는/말 둥).

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

How to form it

When Form Example
Present adnominal pair -는 둥 마는 둥 먹는 둥 마는 둥 / 듣는 둥 마는 둥
Past adnominal pair -(으)ㄴ 둥 만 둥 한 둥 만 둥
Prospective pair -(으)ㄹ 둥 말 둥 갈 둥 말 둥

-는 둥 마는 둥 marks half-doing — barely / half-heartedly.

우리말샘 둥 「004」. Not a clean yes. Not a clean no.

Why this is hard

English kind of is vague. Korean locks a paired frame: do-둥 + not-do-둥. Learners write only one half, or confuse it with pretend -는 척하다.

What it does

You say the action happened only faintly — as if done and not done.

밥은 먹는 둥 마는 둥 했어요.
이야기는 듣는 둥 마는 둥이에요.
숙제는 하는 둥 마는 둥이었죠.
잠은 자는 둥 마는 둥 잤어요.

Forms

Adnominal + 둥 + negative twin 마는/만/말 둥.

먹다 → 먹는 둥 마는 둥
하다 → 하는 둥 마는 둥
가다 → 갈 둥 말 둥

When not to use it

Do not use it for full refusal — say you did not do it.

Do not use it for proud complete success.

Do not swap in 척하다 when you mean weak effort rather than staged pretence.

Neighbours — and why they differ

FormWhy it is not this slot
-는 척하다Pretend performance.
-기만 하다Only does that — limitation.

Ask: am I saying it was only half-done? If yes, -는 둥 마는 둥. If staged pretend, use 척하다.

Do not confuse it with

Quick check

No sign-up, no score saved — just see if it stuck.

1. Dinner happened only faintly — a few bites, no real meal — and you want the half-done paired frame, not a clean finish. Which line fits?

2. Which line uses the past adnominal pair -(으)ㄴ 둥 만 둥 from the forms table?

3. They were putting on an act of eating for the camera — that is -는 척하다. You mean the meal itself was only half-done. Which line fits?

Tone?

Often critical or descriptive of weak effort — meals, listening, studying.
