Grammar
N와/과
Meaning
BeginnerN wa/gwa
와/과 joins two nouns into a single phrase, the way English 'and' joins two nouns. It links nouns only: to join two clauses or two verbs, Korean uses -고 instead. The same particle has a second job — marking the other party in a two-sided action or comparison (친구와 싸우다 'quarrel with a friend', 작년과 비교하면 'compared with last year') — and there English switches to 'with'.
Form
과 goes after a noun ending in a consonant (선율과) and 와 after one ending in a vowel (친구와) — the consonant-final noun takes the heavier form, exactly as with 은/는 and 이/가. In a list of three or more, every noun but the last carries it: 밥과 국과 반찬. Case marking then goes on the last noun only, for the phrase as a whole: 빵과 우유를 샀습니다. 하고 and (이)랑 do the same work in speech, 하고 neutrally and (이)랑 casually; 와/과 is the written, formal choice.
Examples
저는 빵과 우유를 샀습니다.
I bought bread and milk.
Common mistakes & nuance
Two traps. First, 와/과 cannot join verbs or clauses — 'ate and left' is 먹고 나갔다, and there is no 먹와. Second, some verbs require their other party to be marked with 와/과 and reject 을/를 for it: 친구와 싸웠다, 친구와 결혼했다, 작년과 다르다 are Korean, while 친구를 싸웠다 is not. 만나다 is the exception a learner meets first, since both 친구와 만나다 and 친구를 만나다 are fine.
Similar grammar
- -고
The division is by what is being joined: 와/과 joins nouns, -고 joins clauses and verbs. 빵과 우유 is a phrase; 빵을 먹고 우유를 마셨다 is two clauses. Korean will not let one stand in for the other, which is why an English 'and' has to be sorted into one kind or the other before it can be translated.
- 명사 + 와/과 함께
Adding 함께 after 와/과 makes accompaniment explicit — 'together with N' rather than a bare list — and it is the form news writing uses when two things happen side by side. The particle on its own can be read either way, as a list or as a partner; 함께 removes that ambiguity.
