Dependent Clause
A dependent clause is a clause that provides a sentence element with additional information, but which cannot stand alone as a sentence. A dependent clause can either modify an adjacent clause or serve as a component of an independent clause. Some grammarians use the term subordinate clause to refer only to adverbial dependent clauses.
The different types of dependent clauses include content clauses (noun clauses), relative (adjectival) clauses, and adverbial clauses.
In Indo-European languages, 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 serve as adverbs.
In the following examples, the adverbial clauses are bold and the subordinating conjunctions are italicized:
- Wherever she goes, she leaves her luggage (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.)
A subordinating conjunction can also introduce a noun clause:
- I know that he likes me. (The noun clause that he likes me serves as the object of the main-clause verb know.)
Another type of dependent word is the relative pronoun. Relative pronouns begin dependent clauses known as relative clauses; these are adjective clauses, because they modify nouns. In the following example, the relative clause is bold and the relative pronoun is 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 pronoun one.)
A relative adverb plays the part of an adverb in a relative clause, as in
- That is the reason why I came. (The relative clause why I came describes the noun reason, and within the relative clause the adverb why modifies the verb came.)
- That is the place where he lives. (The relative clause where he lives describes the noun place, and within the relative clause the adverb where modifies the verb lives.)
An interrogative word can serve as an adverb in a noun clause, as in
- No one understands why you need experience. (The noun clause why you need experience functions as the direct object of the main-clause verb "understands", and within the noun clause why serves as an adverb modifying need.)
