馬鹿
baka[ba̠ka̠]
The English phrase "you are stupid" is expressed in Japanese as 馬鹿 (baka).
馬鹿 means "stupid" or "idiot". While it can mean 'stupid', in many contexts it is used as a lighthearted or teasing way to call a friend an "idiot".
Which one should you use?
While 馬鹿 is used nationwide, the word 阿呆 is a common alternative that is often used more affectionately in the Kansai region (Osaka area) than in Tokyo.
What mistakes should you avoid?
English speakers often assume they can use 馬鹿 freely, but it is considered an insult and can be quite offensive if used toward a stranger or a superior.
Did you know?
- Some linguists believe 馬鹿 is actually a Japanese transcription of the Sanskrit word moha, which means 'folly'.
- Using 馬鹿 toward a superior in a Japanese workplace is a grave social error that goes beyond a simple insult.
Examples in context
