-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.
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
| Form | Why it is not this slot |
|---|---|
| -고 | Plain listing — lighter. |
| -을뿐더러 | Not only… but also — ending, similar job. |
| -지만 | Contrast — 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?
