Expert writing Tips

Best practice

Avoid using "comprised of". The correct usage is either "comprised" (without "of") or "composed of". Consider using "consisted of" or "made up of" for clarity.

Common error

Many writers incorrectly use "comprised of". Remember that "comprised" means 'to consist of'. Therefore, "comprised of" is redundant. Use "comprised" alone or replace the phrase with "consisted of" or "made up of".
