How it works

Look at the picture: he has lost his wallet. How does he feel? This expression conveys “Oh no, what a shame!”

Use it to express regret or disappointment when you accidentally lose something or something unfortunate happens.

The ordinary past tense simply reports what happened. Adding 「しまいました」 also conveys the speaker’s regret.

Attach it to the verb’s て-form: なくして+しまいました. Here, we are talking about something that has already happened.

「落としてしまいました」 means you accidentally dropped something. The speaker dropped their phone and feels upset about it.

「置いてきてしまいました」 means you left your bag there. It expresses regret about forgetting to take it with you.

When someone asks what is wrong, use this expression to explain that you lost your wallet and let them hear your regret.
