와/과: 'And' / 'With' (Written) | Korean Grammar

와/과 is Korean's neutral, faintly formal particle for joining nouns. It does two jobs that English keeps separate: it lists ("A and B" — 사과와 바나나, "apples and bananas") and it marks a companion ("with" — 친구와 함께, "together with a friend"). One particle, both meanings. It is the version you meet in textbooks, newspapers, signage, and careful writing, and it has one quirk that trips up nearly everyone: its allomorph is backward from the particles you have already learned. This page fixes that quirk, draws the line between "and" and "with," and places 와/과 on the register ladder against its spoken cousins.

What 와/과 does

Put 와/과 between two nouns and it strings them into a list; put it after one noun and pair it with a movement or shared action and it means "with that person." The particle itself does not tell you which — context does, a point we return to below and treat in full on the with-vs-and page.

저는 사과와 바나나를 샀어요.

jeoneun sagwawa bananareul sasseoyo

I bought apples and bananas. (listing)

선생님과 이야기했어요.

seonsaengnimgwa iyagihaesseoyo

I talked with the teacher. (companion)

한국어와 일본어를 공부해요.

hangugeowa ilboneoreul gongbuhaeyo

I study Korean and Japanese. (listing)

In the listing use, note that 와/과 attaches only to the first noun; the last noun in the list then takes whatever particle the sentence needs (여기서 바나나 takes the object marker 를). Korean does not repeat "and" before the final item the way careful English does — 사과와 바나나 is literally "apple-and banana," and that is complete.

The allomorph runs backward — burn this in

Every case particle you have learned so far picks its shape one way: the "easy-to-say" consonant-initial form goes after a vowel, and the vowel-initial form goes after a consonant, so the sounds interleave smoothly. 이/가, 을/를, 은/는 all follow that logic. 와/과 does the opposite, and the reason is historical, not phonetic — you simply have to learn it as an exception.

Noun ends in…	Use	Example
a vowel	와	사과와, 친구와, 우유와
a consonant (받침)	과	책과, 물과, 선생님과

💡

Reverse your instinct. For 이/가 you say "vowel → 가" (the consonant form). For 와/과 it is "vowel → 와" (the vowel form). Anchor it on one pair you will never forget — 친구와 (friend, ends in a vowel → 와) versus 책과 (book, ends in 받침 → 과) — and check every new noun against it.

빵과 우유를 아침으로 먹어요.

ppanggwa uyureul achimeuro meogeoyo

I have bread and milk for breakfast. (빵 ends in a consonant → 과; 우유 in a vowel → 와 elsewhere)

물과 불은 상극이에요.

mulgwa bureun sanggeug-ieyo

Water and fire are opposites. (물 ends in ㄹ → 과)

부모님과 함께 살아요.

bumonimgwa hamkke sarayo

I live together with my parents. (부모님 ends in ㅁ → 과, companion reading)

와/과 joins nouns only — never clauses

This is the boundary that matters most for accuracy. 와/과 is a noun-linker. It can join 사과 to 바나나, but it can never join one sentence or verb to another. English "and" is greedy — it links nouns ("bread and milk"), verbs ("came and went"), and whole clauses ("I ate and I left") all with the same word. Korean refuses to do this. To join actions or clauses, you leave the particle world entirely and use a connective ending on the verb, chiefly -고.

밥을 먹고 커피를 마셨어요.

babeul meokgo keopireul masyeosseoyo

I ate and drank coffee. (clauses joined by verb ending -고, not 와/과)

So the division of labor is clean: nouns get 와/과 (or its spoken cousins), verbs and clauses get -고 and friends. The moment the thing you want to join is an action, 와/과 is off the table. The full treatment of clause-level "and" lives on the -고 connective page.

Register: 와/과 is the bookish one

와/과 is not archaic and not stuffy, but it is the written / formal member of Korea's three-way "and/with" system. You will see it in newspaper prose, official notices, academic writing, formal speeches, and set phrases — and you will hear it in careful or public speech. In ordinary conversation, though, Koreans usually reach for 하고 (neutral) or (이)랑 (casual) instead. Saying 친구와 함께 카페에 갔어요 to a friend is not wrong, but it can sound like you are narrating your own documentary.

대통령은 국민과 소통해야 한다.

daetongnyeong-eun gungmingwa sotonghaeya handa

The president must communicate with the people. (news / formal, 한다체)

이 제품은 물과 기름으로 만들어집니다.

i jepumeun mulgwa gireumeuro mandeureojimnida

This product is made with water and oil. (formal / written)

💡

The three "and/with" particles form a register ladder: 와/과 (written, formal) › 하고 (neutral, everyday spoken) › (이)랑 (casual, intimate). They mean the same thing; pick the rung that matches the room. Reach for 와/과 in essays, emails to strangers, and anything printed — see 하고 and (이)랑 for the spoken rungs.

The "with" reading, and 같이 / 함께

When 와/과 means "with (a companion)," it very often teams up with the adverb 같이 or 함께 ("together") to make the accompaniment explicit — 친구와 같이, 가족과 함께. Without them, 친구와 영화 could in principle be read as "a friend and a movie" (a list); adding 같이 forces the "together with" reading.

친구와 같이 영화를 봤어요.

chinguwa gachi yeonghwareul bwasseoyo

I watched a movie together with a friend.

The full logic of when 와/과 is "and" versus "with," and how 같이/함께 disambiguate, gets its own page: with vs and, and 같이/함께.

Common Mistakes

1. Getting the allomorph backward. Because 와/과 flips the usual pattern, learners who trust their 이/가 instinct produce the wrong form. A consonant-final noun takes 과.

❌ 책와 공책을 샀어요.

Wrong — 책 ends in a consonant, so it must take 과, not 와.

✅ 책과 공책을 샀어요.

chaekgwa gongchaegeul sasseoyo

I bought a book and a notebook.

2. The other direction — 과 after a vowel. A vowel-final noun takes 와.

❌ 사과과 배를 먹었어요.

Wrong — 사과 ends in a vowel, so it must take 와.

✅ 사과와 배를 먹었어요.

sagwawa baereul meogeosseoyo

I ate an apple and a pear.

3. Using 와/과 to join verbs or clauses. 와/과 links nouns only; actions link with -고.

❌ 아침을 먹었어요와 학교에 갔어요.

Wrong — you cannot join two clauses with 와/과; use the verb ending -고.

✅ 아침을 먹고 학교에 갔어요.

achimeul meokgo hakgyo-e gasseoyo

I ate breakfast and went to school.

4. Over-formalizing casual talk. In a text to a friend, 와/과 sounds like a press release; use 하고 or (이)랑.

❌ 나 지금 친구와 카페에 있어.

Too bookish for a text — a friend would write 친구랑 or 친구하고.

✅ 나 지금 친구랑 카페에 있어.

na jigeum chingurang kape-e isseo

I'm at a café with a friend right now. (casual)

5. Repeating the particle before the last item, English-style. 와/과 goes only on the non-final nouns; the last item takes the sentence's own particle.

❌ 사과와 바나나와를 샀어요.

Wrong — don't stack 와 onto the final noun; 바나나 just takes the object marker.

✅ 사과와 바나나를 샀어요.

sagwawa bananareul sasseoyo

I bought apples and bananas.

Key Takeaways

와/과 both lists ("A and B") and marks a companion ("with"), with context — often plus 같이/함께 — deciding which.
The allomorph is backward: 와 after a vowel (친구와), 과 after a consonant (책과). Anchor it on 친구와 / 책과.
It joins nouns only. For "and" between verbs or clauses, use the ending -고 (먹고 갔어요), never 와/과.
Register: 와/과 is the written / formal rung; everyday speech prefers 하고 (neutral) or (이)랑 (casual).
