Expert writing Tips

Best practice

Always use "an instance of" (singular) or "instances of" (plural) to ensure grammatical correctness. Verify whether you are referring to a single example or multiple examples.

Common error

Avoid using "an instances of". Remember that "an" is used before singular nouns. If you intend to refer to multiple instances, use "instances of" without "an".
