アホ

意味

Idiot, fool, or dummy — a blunt but sometimes affectionate way of calling someone stupid.

アホ is one of the two foundational 'idiot' words in Japanese alongside バカ. While historically more associated with Western Japan (Kansai), it is now understood and used nationwide. In Kansai, アホ is the milder, more affectionate term (while バカ is harsh), but in Tokyo and Eastern Japan, the nuance can be reversed. Among friends, アホ is often used warmly to tease. It can also express exasperated fondness for someone's silly behaviour.

例文

1. そんなの信じるとかアホちゃう？
2. アホなことばっかりやってないで勉強しろ。
3. あいつアホみたいに明るいから、一緒にいると楽しい。
