-는 데다가

-는 데다가: And On Top Of That — Stacking One Fact

Connective: add a second fact onto the first — and what’s more / on top of that.

Before this, make sure you know: -는데① , -아요 / -어요

How to form it

When Form Example
Verb (present) + -는 데다가 -는 데다가 비가 오는 데다가 / 일이 많은 데다가
Adjective / past + -(으)ㄴ 데다가 -(으)ㄴ 데다가 바쁜 데다가 / 예쁜 데다가 / 온 데다가
Noun + 인 데다가 -인 데다가 학생인 데다가

-는 데다가 means and on top of that — stacking one fact onto another.

Why this is hard

It neighbours -을뿐더러 and listing -고. Learners use bare -고 for every stack and miss the ‘plus another point’ weight of 데다가. The noun 데 is the landing pad for the added fact.

What it does

You add a second reason or quality on top of the first.

바쁜 데다가 피곤해요.
싼 데다가 맛있어요.
길이 먼 데다가 비까지 와요.
친절한 데다가 실력이 좋아요.

Forms

Adnominal + 데다가 — -는 데다가, -(으)ㄴ 데다가, past -던/었던 shapes as taught.

When not to use it

Do not replace every light -고 with it. Do not write 바쁘다 데다가 without the adnominal. Do not use it for contrast instead of addition.

Neighbours — and why they differ

FormWhy it is not this slot
-고Plain listing — lighter.
-을뿐더러Not only… but also — ending, similar job.
-지만Contrast — opposite neighbourhood.

Complaints and praise both stack well here. Keep the second clause in the same direction as the first.

Classroom examples should keep the meaning concrete: one clear scene beats three vague glosses. If a neighbour form already says the same thing more lightly, prefer the lighter tool unless register demands this one.

Ask: am I stacking ‘A, and on top of that B’? If yes, -는 데다가. If you only need light and, use -고.

Quick check

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

1. You want to pile a second same-direction complaint on top of being busy — not a light ‘and’, not a contrast. Which line?

2. Rain is falling now — which line uses the present verb shape 오는 데다가 from the forms table?

3. Same stacking job — which hooks the first fact onto the clause, rather than using free-adverb 게다가?

Common questions

Dictionary?

Build: 데 「002」 (‘affair/thing’) + 에다가 「002」 (added target). Educational pattern -는/-(으)ㄴ/인 데다가 stacks a second fact.

Vs 게다가?

게다가 is a free adverb (‘besides’). -는 데다가 hooks onto the first clause.

Same direction?

Usually both clauses lean the same way (both good or both bad).

Vs -는데?

-는데 often backgrounds. -는 데다가 piles weight on top.
