Expert writing Tips
Best practice
When followed by a noun, make sure you specify which kind of familiarity you're referring to (e.g. "not familiar with the author's work") for clarity.
Common error
Avoid using "not familiar" when you actually mean you're uninterested. Familiarity refers to knowledge or experience, not necessarily liking something. Use stronger terms like "dislike" or "uninterested" when expressing aversion.
