もう結構です。
Mō kekkō desu.
No more, thank you.
- Word for word
- “It is already sufficient.”
- Politeness: Formal
- Honorific or humble language, or a set business phrase. Customer service, email, speeches.
- When you would say it
- Declining a refill or a second serving.
- Worth knowing
- 結構です can also mean “yes, that is fine”. It is ambiguous, so shake your head or add もう (already) as here.
