이나 / 나
이나/나 Korean Grammar: Or, At Least, As Many As
Particle: choose between nouns, suggest a fallback, or emphasize that an amount is larger than expected.
How to form it
| When | Form | Example |
|---|---|---|
| Noun with batchim | N + 이나 | 물 → 물이나 / 집 → 집이나 |
| Noun without batchim | N + 나 | 커피 → 커피나 / 사과 → 사과나 |
| Settling / 'at least this' | N + 이나/나 | 물이나 마실래요 / 라면이나 먹자 |
| A surprisingly large amount | Number or amount + 이나/나 | 세 시간이나 기다렸어요 |
이나 / 나 most often means or after a noun. It can also mean at least that when suggesting a fallback, or emphasize an amount as surprisingly large.
The same short particle therefore appears in three common situations. The word before it—and the whole sentence—tells you which meaning is intended.
커피나 차 마실래요?
Would you like coffee or tea?
아파트나 주택 중에 어디에 살고 싶어요?
Among apartments or houses, where do you want to live?
물이나 주세요.
Just water, please. / Water will do.
세 시간이나 기다렸어요.
I waited as long as three hours.Forms
| Noun ending | Particle | Example |
|---|---|---|
| batchim | 이나 | 물이나, 집이나 |
| vowel | 나 | 커피나, 사과나 |
빵이나 밥 bread or rice
버스나 지하철 bus or subwayTwo jobs, one particle
| Reading | Feel | Example |
|---|---|---|
| Plain alternative | A or B | 커피나 차 |
| Settling / at least | less-than-ideal pick | 라면이나 먹자 |
You do not need a special conjugation — context decides. If the speaker sounds resigned, you are hearing the second sense.
A large amount: “as many as”
After a number or amount, 이나/나 can show that the speaker finds it surprisingly large.
세 시간이나 기다렸어요.
I waited as long as three hours.
커피를 다섯 잔이나 마셨어요.
I drank as many as five cups of coffee.This is not a choice between options. The amount before 이나/나 is the important part.
Not -거나
| Form | Attaches to | Example |
|---|---|---|
| 이나 / 나 | noun | 아파트나 오피스텔 |
| -거나 -거나 | verb / adjective | 사거나 빌려요 |
Keep the attachment rule straight: nouns take 이나/나, while actions and states take -거나.
Not 하고
과/와, 하고 하고 / 와/과 is and (or accompaniment). 이나/나 is or.
커피하고 차 마실래요? offers both. 커피나 차 마실래요? offers a choice.

Common questions
이나 or 나?
Batchim noun → 이나 (집이나). Vowel-final noun → 나 (커피나). Same split pattern as 이/가 and 을/를.
Is it the same as 하고?
No. gwa-hago lists or accompanies (A and B). 이나/나 picks among options (A or B).
When is the 'settling' reading natural?
When the noun is a fallback: 라면이나 먹자 (let’s at least have ramyeon), 물이나 주세요. Tone and context carry it — not every 이나 is disappointed.
Can I use 이나 on verbs?
No. Verb alternatives take geona -거나. *가이나 와요 is not Korean.
What does 이나 mean after a number?
It can mark an unexpectedly large amount: 세 시간이나 기다렸어요 means ‘I waited as long as three hours.’ Context tells this apart from a choice.
