ちゃう

Japanese

Etymology 1

Contraction of ～てしまう (-te shimau).[1][2][3]

/-te ɕimau/ → /-t͡ɕimau/ → /-t͡ɕau/

Suffix

ちゃう • (-chau) 

1. (colloquial) contraction of ～てしまう

Usage notes

Attaches to what would be the regular -te form for the verb. Examples:

• 書く (kaku) → 書いて (kaite) → 書いてしまう (kaite shimau) → 書いちゃう (kaichau)
• 待つ (matsu) → 待って (matte) → 待ってしまう (matte shimau) → 待っちゃう (matchau)

If the regular -te form of the verb results in voicing from -te to -de, that voicing carries over to the abbreviated form.

• 呼ぶ (yobu) → 呼んで (yonde) → 呼んでしまう (yonde shimau) → 呼んじゃう (yonjau)

Synonyms

• ちまう (chimau)
• (Kansai) てまう (temau)
