# alreadyCancelled

An error describing a translation session that you’ve cancelled before, which prevents the session from producing additional results.

```
static let alreadyCancelled: TranslationError
```

## Discussion

A [`TranslationSession`](/documentation/Translation/TranslationSession) instance throws this error when you call one of its translate methods after calling its [`cancel()`](/documentation/Translation/TranslationSession/cancel()) method.
