Comprise and compose
These words often end up in the wrong place. A simple trick is to remember that "comprised" means "composed of." Consider:
His house is comprised of bricks, plaster and wood.
Since comprised means "composed of," we can substitute "composed of" in this sentence and see it is incorrect:
His house is composed of of bricks, plaster and wood.
It should read one of two ways:
His house comprises bricks, plaster and wood. His house is composed of bricks, plaster and wood.
His house comprises bricks, plaster and wood.
His house is composed of bricks, plaster and wood.
