What does it mean word for word?
The core part of the phrase, 結構, literally means "fine", "sufficient" or "splendid".
Which one should you use?
Depending on the context and intonation, 結構です can mean both "no thank you" (I am fine as I am) and "yes, that is fine" (it is sufficient/good).
Is there a formal and an informal way to say it?
結構です is a polite way to decline an offer, making it suitable for use with strangers or in formal settings. For a more formal way to refuse something, you can also say Dōmo, kekkō desu. In informal situations, you might use the phrase Dōmo, chotto… to politely decline an offer.
How do you pronounce it?
kekkō desu
What mistakes should you avoid?
English speakers may mistakenly use 結構です to mean "it is wonderful" in a way that sounds overly stiff or unnatural in casual conversation.
Did you know?
- The word 結構 is composed of kanji meaning 'build' and 'structure', originally referring to a well-constructed building.
- In a business context, a direct 'no' is so avoided that 結構です might be replaced by 検討します, which means 'I will consider it' but often functions as a polite 'no'.
- In Japan, a polite 'no' is often accompanied by a small wave of the hand in front of the face or a slight tilt of the head to soften the refusal.
