Expert writing Tips
Best practice
When using "which is comprised of", ensure clarity by clearly defining the components that make up the subject you're describing.
Common error
Avoid using "comprised of" when you mean "composed of" or "consists of". "Comprise" means to include or contain; the parts comprise the whole, not the other way around. So, it is better to say "The whole comprises the parts.", instead of "The whole is comprised of parts."
