Is it "comprised of" or "composed of"?

"Composed of." Strict usage treats "comprised of" as an error — the whole comprises the parts directly.

What's the difference between "comprise" and "compose"?

The whole comprises the parts. The parts compose the whole. Opposite directions.

Quick answer Canonicalizes to Comprise vs. Compose

Can I say "comprised of"?

i · AnswerOne line, no lecture

In casual writing, yes — it is everywhere. In careful prose, use composed of or comprises instead.

ii · A little moreWhy this is the one to keep

"Comprised of" is so common that many dictionaries now note it as standard. But editors still flag it, because comprise on its own already means "contain." If you want to dodge the argument entirely, write composed of.
