NOUN CLAUSE

   

     See The Sentence for definitions of sentence, clause, and dependent clause.

A sentence which contains just one clause is called a simple sentence.

A sentence which contains one independent clause and one or more dependent clauses is called a complex sentence. (Dependent clauses are also called subordinate clauses.)

There are three basic types of dependent clauses: adjective clauses, adverb clauses, and noun clauses. (Adjective clauses are also called relative clauses.)

This page contains information about noun clauses. Also see Adjective Clauses and Adverb Clauses.

A. Noun clauses perform the same functions in sentences that nouns do:

A noun clause can be a subject of a verb:

What Billy did shocked his friends.

A noun clause can be an object of a verb:

Billy’s friends didn’t know that he couldn’t swim.

A noun clause can be a subject complement:

Billy’s mistake was that he refused to take lessons.

A noun clause can be an object of a preposition:

Mary is not responsible for what Billy did.

A noun clause (but not a noun) can be an adjective complement:

Everybody is sad that Billy drowned.
