Dependent clause

From Wikipedia, the free encyclopedia

A dependent clause (or subordinate clause) cannot stand alone as a sentence. In itself, a dependent clause does not express a complete thought; therefore, it is usually attached to an independent clause. Although a dependent clause contains a subject and a predicate, it sounds incomplete when standing alone.

[edit] Dependent words

A dependent clause usually begins with a dependent word. One kind of dependent word is a subordinating conjunction. Subordinating conjunctions are used to begin dependent clauses known as adverbial clauses which act like adverbs. In the following examples, the adverbial clauses are bold and the subordinating conjunctions are italicized:

Wherever she goes, she leaves a piece of luggage behind. (The adverbial clause wherever she goes modifies the verb leaves.)

Bob enjoyed the movie more than I did. (The adverbial clause than I did modifies the adverb more.)

Another type of dependent word is the relative pronoun. Relative pronouns begin dependent clauses known as adjective clauses, which act like adjectives, or noun clauses, which act like a nouns. In the following examples, the dependent clauses are bold and the relative pronouns are italicized:

The only one of the seven dwarfs who does not have a beard is Dopey. (The adjective clause who does not have a beard describes the noun one.)

No one understands why experience is something you don't get until just after you need it'. (The noun clause why experience is something you don't get until just after you need it functions as a direct object.)

[edit] Dependent clauses and sentence structure

A sentence with an independent clause and one or more dependent clauses is referred to as a complex sentence. One with two or more independent clauses and one or more dependent clauses is referred to as a compound-complex sentence.

My sister cried because she scraped her knee. (complex sentence)
- Subjects: My sister, she
- Predicates: cried, scraped her knee
- Subordinating conjunction: because

When they told me I won the contest, I cried, but I didn't faint. **(compound-complex sentence)
- Subjects: they, I, I, I
- Predicates: told me, won the contest, cried, didn't faint
- Subordinating conjunctions: When, that (understood)
- Coordinating conjunction: but

The above sentence actually contains two dependent clauses. "When they told me" is one; the other is "(that) I won the contest." The "that" is understood to precede the "I won" and functions as a subordinating conjunction.

[edit] Non-finite dependent clauses

Dependent clauses may be headed by an infinitive or other non-finite verb form. In these cases, the subject of the dependent clause may take a non-nominative form. Examples:
