テキトー

• 読み: テキトー
• ローマ字: tekitō
• 漢字の分解: From 適当: 適 (fit/suitable) + 当 (hit/right) → ironic slang reversal to mean 'careless/sloppy'
• 発音: /te.ki.toː/

意味

Half-assed, sloppy, or done without care — the ironic casual flip of the formal word meaning 'appropriate.'

The formal word 適当 (tekitō) means 'appropriate' or 'suitable,' but in casual speech テキトー has ironically flipped to mean the opposite: careless, slapdash, and half-hearted. When someone does something テキトーに, they are winging it without much thought or effort. The katakana spelling signals the casual, slangy meaning. Interestingly, sometimes テキトー can carry a positive 'relaxed' nuance — like not sweating the small stuff.

例文

1. テキトーにやったレポートがなぜか高評価だった。
2. あいつの仕事テキトーすぎてフォローが大変なんだよ。
3. テキトーに選んだ店がめちゃくちゃ当たりだった。

起源と歴史

From 適当 (tekitō, appropriate/suitable). The ironic reversal of meaning — from 'just right' to 'careless' — happened through casual speech, where saying something is 適当 with a dismissive tone came to imply 'whatever, good enough.' The katakana spelling テキトー emerged to distinguish the slangy meaning.
