Use coordination and subordination to indicate the relationships among sentence elements.

E8-a Use coordination to join sentence elements that are equally important.

H-42

Writers use coordination to bring together in one sentence two or more elements of equal importance to the meaning. These elements can be words, phrases, or clauses, including independent clauses within the same sentence.

E8-b Use subordination to indicate that one sentence element is more important than other elements.

Writers frequently subordinate information within a single sentence. The most important information appears in an independent clause, and the less important or subordinate information appears in words, phrases, or dependent clauses attached to the independent clause or integrated into it.
