Expert writing Tips

Best practice

When intending to refer to a non-specific quantity that is part of a whole, use the correct grammatical structure: either "a portion of" for a singular portion or "portions of" for multiple portions.

Common error

Avoid using "a portions of" as it incorrectly combines a singular article ("a") with a plural noun ("portions"). Always ensure agreement between articles and nouns in your writing.
