These five worksheets on the homophones compliment and complement are actually the first I ever wrote. You’ll notice that I set up the worksheets to use these words as nouns. Because it turns up as a term of art in any number of grammar and style manuals, I wanted students to learn the use of complement as a grammatical term. It’s used in all kinds of ways, even sometimes to describe a predicate, which I think is better called, simply, a predicate.
However, as a means of describing both the direct objects and the indirect objects of verbs, I think this is a very good word indeed. I’m fairly certain I placed all five of these worksheets as do-now exercises at various places in a thirteen-lesson unit on verbs. If you use them the same way, you may want to mention to students that both of these words can be used as verbs; both are used transitively.
