Learn Japanese grammar: (te shimau) & (chau). Meaning: to do something by accident, to finish completely.

This may in some cases also express regret, but not always.

てしまう (te shimau)

This is the standard version:

  • てしまう = to do by accident / to finish
  • てしまった = did by accident / finished
  • てしまいました = did by accident / finished (more formal)

ちゃう/じゃう (chau / jau)

This is the more casual version, which instead uses a verb’s stem form:

  • ちゃう = to do by accident / to finish (casual)
  • ちゃった = did by accident / finished (casual)

NOTE: If the verb’s dictionary form ends with ぶ (bu) , む (mu) , ぬ (nu) or ぐ (gu), it becomes じゃう (jau) or じゃった (jatta).

  • じゃう = to do by accident / to finish (casual)
  • じゃった = did by accident / finished (casual)
