Expert writing Tips

Best practice

When using "comprised mostly of", ensure that the other components are not entirely negligible. If the subject is almost entirely one thing, consider using "comprised entirely of" or "primarily comprised of" instead.

Common error

Avoid using "comprised of" when you mean "composed of". Although often used interchangeably, "comprise" means 'to include' or 'contain', while "compose" means 'to constitute' or 'to make up'. It is more technically correct to say something is "composed mostly of" something else.
