Expert writing Tips
Best practice
Avoid using "define about" in formal writing. Instead, use "define" followed by the term or concept you are defining. For example, "Define sustainability" is grammatically correct.
Common error
A common mistake is to add "about" after "define", which is grammatically redundant. Always use "define" directly followed by the term you're clarifying. For instance, instead of writing, "Define about the term", write "Define the term".
