haru Korean › Grammar › Level 2A › A-(으)ㄴ데 · V-는데 · N인데

A-(으)ㄴ데 · V-는데 · N인데 — giving the background or a contrast — '…, so …' · '…, but …'

Giving the background or a contrast — '…, so …' · '…, but …'. Korean grammar for upper beginner learners — Level 2A, lesson 9: 문의할 게 있는데요 (I have a question — calling to ask).

What it means

-는데 joins two sentences: the first part gives the background that the second part needs. 표가 있는데 같이 가요 'I've got tickets — let's go together'; 배가 고픈데 밥 먹으러 갈까요? 'I'm hungry — shall we go and eat?' Unlike -아서/어서, it can come before a suggestion, a question or a request, which is why Koreans use it all the time before asking for something: 이 단어를 모르는데 좀 가르쳐 주세요. It is also the natural way to introduce someone or something and add one more fact: 제 친구인데 같은 학교에 다녀요. And it can put two facts side by side, like a soft 'but': 이 식당은 맛있는데 좀 비싸요 (-지만 is the clearer 'but'). The ending depends on the word, just like the describing forms of Lesson 2: adjectives take -(으)ㄴ데 — 작은데, 비싼데, with the usual changes (춥다 → 추운데, 멀다 → 먼데); verbs and 있다/없다 take -는데 — 가는데, 먹는데, 사는데, 있는데, and so do 맛있다 and 재미있다; nouns take 인데 — 학생인데, 친구인데. -고 싶다 works like an adjective: 가고 싶은데. In the past, verbs, adjectives and nouns all take -았/었는데: 갔는데, 비쌌는데, 학생이었는데.
