Expert writing Tips
Best practice
When writing, consider the context and adjust your vocabulary choices so as to find the best word to reflect the kind and completeness of your knowledge. For example, instead of writing "I knew about the incident", if your knowledge was vague write "I had heard of the incident."
Common error
While acceptable, repeatedly using "I knew about" in formal documents can sound repetitive. Vary your sentence structure by using synonyms like "I was aware of" or "I had knowledge of" to maintain a professional tone.
