Expert writing Tips
Best practice
When using "had carried out", ensure that the context clearly establishes a past perfect tense, indicating an action completed before another point in the past. For instance, "Before the audit began, the team had carried out a thorough review of the records."
Common error
Avoid using the simple past tense ("carried out") when the past perfect ("had carried out") is necessary to show the sequence of events. Using "carried out" without "had" can obscure the timeline, making it unclear which action occurred first. Instead of saying "The team carried out the review before the audit began", clarify the sequence by stating "The team had carried out the review before the audit began."
