かっこいい

• Reading: かっこいい
• Romaji: kakkoii
• Pronunciation: /kak.ko.iː/

Meaning

Cool, handsome, or attractive — the go-to compliment for someone or something that looks impressive or stylish.

One of the most essential Japanese compliments, かっこいい covers everything from a person's looks to their car, guitar solo, or brave actions. Originally from 格好いい (good appearance), the colloquial かっこいい spelling has become standard. It applies to both people and things, and while it traditionally described men, modern usage extends to women, objects, and abstract concepts like ideas or decisions.

Examples

1. あの人めっちゃかっこよくない？誰だろ。 That person is super hot, don't you think? I wonder who they are.
2. ギター弾けるのかっこいいなぁ。 Being able to play guitar is so cool.
3. 新しいスニーカーかっこいいじゃん、似合ってるよ。 Your new sneakers look awesome — they really suit you.
