1.15 Clauses and Phrases

Clauses include both subjects and verbs that work together as a single unit. When they form stand-alone sentences, they’re called independent clauses. An independent clause can stand alone or can be used with other clauses and phrases. A dependent clause also includes both a subject and a verb, but it must combine with an independent clause to form a complete sentence.

Adjective clause (also called a relative clause)

Begins with a relative pronoun (that, who, whom, whose,which) or a relative adverb (when, where, why); functions as an adjective; attaches to a noun; has both a subject and a verb; tells what kind, how many, or which one

Appositive clause

Functions as an appositive by restating a noun or noun-related verb in clause form; begins with that; typical nouns involved include possibilities such as assumption, belief, conviction, idea, knowledge, and theory

*In some instances, the relative pronoun or adverb can be implied (e.g., “The day he lost his watch was an unlucky day”).
