Expert writing Tips
Best practice
Ensure that "concern" is preceded by an article ("a" or "the") or an adjective to properly function as a noun in the sentence. For example, use "that was a concern" or "that was my main concern".
Common error
Avoid using "concern" directly after "was" without an article or adjective to specify what kind of concern or whose concern it is. This can lead to grammatically incorrect sentences.
