Expert writing Tips

Best practice

When using "had already known", ensure the context clearly indicates when the knowledge was acquired in relation to another past event. This clarifies the timeline for the reader.

Common error

Avoid using "had already known" when the simple past tense ("knew") is sufficient. The past perfect is necessary only when referencing a prior action or state relative to another point in the past. For example, use "I knew" instead of "I had already known" if there's no prior point of reference.
