N(이)나
Quick answer: N(이)나 means or — either one is fine.
How to form it
No final consonant → 나 · final consonant → 이나 · attaches to nouns only
In Korean: 받침 X → 나 받침 O → 이나 명사에만 붙습니다
What to know
You already know 그리고 for adding one thing to another. (이)나 is different — it puts two things side by side and lets the listener pick. It goes between two nouns, never between two verbs, so «가나 와요» is wrong.
Examples
- 금요일이나 토요일에 모여요.We meet on Friday or Saturday.
- 빵이나 김밥을 먹어요.I eat bread or gimbap.
- 기타나 피아노를 배워요.I learn the guitar or the piano.
