Expert writing Tips
Best practice
Ensure the context provides a clear reference point for the timing of both the realization and the subsequent or related event.
Common error
Avoid using "had realized" when a simple past tense ("realized") is sufficient. "Had realized" is specifically for actions completed before another point in the past. For instance, "I realized I was late" is correct if it's a standalone statement; "I had realized I was late before the meeting started" correctly uses the past perfect.
