Expert writing Tips
Best practice
Ensure that the context clearly indicates a past perfect construction is appropriate. Using "had done before" implies that there is another past action being referenced or implied. Otherwise, a simple past tense may be more appropriate.
Common error
Avoid using "had done before" when a simple past tense is sufficient. The past perfect (had + past participle) is used to indicate that an action was completed before another action in the past. If there's no subsequent past action to compare it to, use the simple past instead.
