하고 / (이)랑: Colloquial 'And / With' | Korean Grammar

Korean has three particles that all mean both "and" (joining two nouns) and "with" (marking a companion): 와/과, 하고, and (이)랑. English keeps "and" and "with" strictly apart — you would never confuse "bread and milk" with "bread with milk" — so the first thing to unlearn is the expectation that these three particles divide up meaning. They don't. All three cover the same two meanings. What separates them is register: how formal or relaxed the moment is. This page owns the two spoken rungs — 하고 and (이)랑 — and shows you how to slide between them by reading the room. The written, bookish rung, 와/과, gets its full treatment on its own 와/과 page.

The register ladder, not a meaning split

Picture a three-rung ladder. At the top sits 와/과, the particle of print and podium: news copy, essays, official notices, careful public speech. In the middle sits 하고, the neutral spoken default you can use with almost anyone without sounding stiff or overly chummy. At the bottom — the intimate rung — sits (이)랑, the one you use with friends, family, and people you have "dropped the formality" with.

Register	Particle	Where it lives
written / formal	와/과	news, essays, notices, speeches
neutral spoken	하고	everyday conversation, most speech
casual / intimate	(이)랑	friends, family, texting

The three sentences below say the identical thing — "I went to a café with a friend" — and differ only in how relaxed the speaker is being. Reading them top to bottom is like watching someone loosen their collar.

친구와 함께 카페에 갔습니다.

chinguwa hamkke kapee gatseumnida

I went to a café together with a friend. (formal / written — 와, 합니다체)

친구하고 카페에 갔어요.

chinguhago kapee gasseoyo

I went to a café with a friend. (neutral spoken — 하고, 해요체)

친구랑 카페 갔어.

chingurang kape gasseo

I went to a café with a friend. (casual — 랑, 반말)

💡

Before you pick a comitative particle, ask "how relaxed is this conversation?" — not "do I mean 'and' or 'with'?" All three do both meanings; the choice is a register dial. 와/과 = writing and formality, 하고 = safe everyday speech, (이)랑 = friends and family.

하고: the neutral rung with no allomorph

하고 is the one you can reach for almost anywhere in speech. Its great mercy for beginners is that it never changes shape: unlike 이/가, 을/를, or 와/과, it does not care whether the noun ends in a vowel or a 받침 (final consonant). Clip it onto any noun exactly as it is.

밥하고 국을 다 먹었어요.

bapago gugeul da meogeosseoyo

I ate all the rice and soup. (listing — 하고 on 밥, ends in a consonant)

친구하고 영화를 봤어요.

chinguhago yeonghwareul bwasseoyo

I watched a movie with a friend. (companion — 하고 on 친구, ends in a vowel)

Notice that 밥하고 is said 받침 ㅂ fuses with the ㅎ of 하고 into an aspirated ㅍ — the same regular aspiration behind 축하 [추카]. The spelling stays 밥하고; only the sound merges. The single form is why 하고 is the low-risk answer whenever you can't decide which comitative a spoken situation wants. For its full mechanics — including the trap where it looks identical to the verb ending -고 — see the dedicated 하고 page.

(이)랑: the intimate rung, and its allomorph

(이)랑 carries a whiff of warmth and closeness. It is what you use with the people you are comfortable with, and it is everywhere in texting, family chatter, and friends talking. Unlike 하고, it does have an allomorph, and this one runs the ordinary way: 랑 after a vowel, 이랑 after a 받침 — the extra 이 is a buffer that keeps two consonants from colliding.

Noun ends in…	Use	Example
a vowel	랑	너랑, 우유랑, 커피랑
a consonant (받침)	이랑	형이랑, 밥이랑, 동생이랑

너랑 나랑 같이 가자.

neorang narang gachi gaja

Let's go together, you and me. (listing — 랑 on 너 and 나, both vowel-final; 반말)

우유랑 빵 주세요.

uyurang ppang juseyo

Milk and bread, please. (listing — 랑 on 우유, vowel-final)

형이랑 놀았어요.

hyeong-irang norasseoyo

I hung out with my older brother. (companion — 이랑 on 형, which ends in ㅇ)

That last example is the one to burn in: 형 ends in a 받침, so it must be 형이랑, never ×형랑. The full allomorphy and feel of this particle live on its own (이)랑 page.

The "with" reading usually leans on 같이 / 함께

Because a single 하고 or (이)랑 could in principle mean either "and" or "with," Korean very often nails down the "with (a companion)" reading by adding the adverb 같이 or 함께 ("together"). 친구랑 영화 on its own could be read as a list ("a friend and a movie"); 친구랑 같이 영화 forces "together with a friend."

주말에 가족하고 같이 등산했어요.

jumare gajokago gachi deungsanhaesseoyo

On the weekend I went hiking together with my family. (하고 + 같이)

동생이랑 함께 청소했어.

dongsaeng-irang hamkke cheongsohaesseo

I cleaned up together with my younger sibling. (이랑 + 함께, 반말)

💡

When you mean "with someone," pin down the accompaniment reading by adding 같이 or 함께: 친구랑 같이, 가족하고 함께. Without them, a bare 랑/하고 between two nouns is more easily read as a plain "A and B" list. The full disambiguation logic is on the with-vs-and page.

Same particle, both jobs — a side-by-side

To drive home that these particles do not split by meaning, here is 하고 doing "and" and "with" in one breath, and (이)랑 doing the same:

점심에 김밥하고 라면을 먹고, 친구하고 카페에 갔어요.

jeomsime gimbapago ramyeoneul meokgo, chinguhago kapee gasseoyo

At lunch I had gimbap and ramen, and went to a café with a friend. (하고 lists, then accompanies)

나랑 언니랑 엄마랑 다 같이 여행 갔어.

narang eonnirang eommarang da gachi yeohaeng gasseo

Me, my older sister, and Mom all went on a trip together. (이)랑 chaining a list, then 같이 for 'together'; 반말)

When the room changes, so should the rung

The one thing to actually get wrong is a register clash — pinning the intimate (이)랑 onto stiff, formal speech, or vice versa. If your verb is in polished 합니다체, the intimate 랑 jars against it; the register-matched choice there is 와/과 (or at most 하고). Conversely, dropping bookish 와/과 into a text to a close friend sounds like you are narrating a documentary about your own life.

Common Mistakes

1. Register clash — casual (이)랑 with formal 합니다체. The intimate particle fights the formal ending. Match the rung to the room.

❌ 부장님이랑 회의를 했습니다.

Clash — intimate 이랑 collides with the formal 했습니다; a report or formal speech wants 부장님과.

✅ 부장님과 회의를 했습니다.

bujangnimgwa hoeuireul haetseumnida

I had a meeting with the department head. (formal / written)

2. Forgetting the 이- after a 받침. (이)랑 needs the buffer 이 after a consonant-final noun.

❌ 형랑 밥 먹었어.

Wrong — 형 ends in a consonant, so the particle must be 이랑.

✅ 형이랑 밥 먹었어.

hyeong-irang bap meogeosseo

I ate with my older brother. (반말)

3. Inventing an allomorph for 하고. 하고 has exactly one form; it never agrees with the noun's ending the way (이)랑 does.

❌ 밥이하고 김치를 먹었어요.

Wrong — 하고 takes no buffer 이; it is simply 밥하고.

✅ 밥하고 김치를 먹었어요.

bapago gimchireul meogeosseoyo

I ate rice and kimchi.

4. Over-formalizing casual talk. In a text to a friend, 와/과 reads like a press release; the spoken rungs fit.

❌ 나 지금 친구와 있어.

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

✅ 나 지금 친구랑 있어.

na jigeum chingurang isseo

I'm with a friend right now. (casual, 반말)

5. Treating "with" as needing a different particle from "and." English instinct says "with" must look different from "and." In Korean it is the same particle; if anything, add 같이/함께.

✅ 친구랑 같이 갔어요.

chingurang gachi gasseoyo

I went together with a friend. (same 랑 as 'and' — 같이 supplies 'together')

Key Takeaways

하고 and (이)랑 are the two spoken particles for both "and" (listing) and "with" (accompaniment); the formal, written rung is 와/과.
The three differ by register, not meaning: 와/과 (formal) › 하고 (neutral spoken) › (이)랑 (casual, intimate). Pick by how relaxed the moment is.
하고 has no allomorph (밥하고, 친구하고). (이)랑 does: 랑 after a vowel (너랑), 이랑 after a 받침 (형이랑) — never ×형랑.
Force the "with" reading by adding 같이 / 함께 (친구랑 같이).
The real error to avoid is a register clash — intimate (이)랑 stapled to formal 합니다체 speech.
