Adverb Clauses

What is an adverb clause?

An adverb clause is a group of words that is used to change or qualify the meaning of an adjective, a verb, a clause, another adverb, or any other type of word or phrase with the exception of determiners and adjectives that directly modify nouns.

Adverb clauses always meet three requirements:

  • First, an adverb clause always contains a subject and a verb.
  • Second, adverb clauses contain subordinate conjunctions that prevent them from containing complete thoughts and becoming full sentences.
  • Third, all adverb clauses answer one of the classic “adverb questions:” When? Why? How? Where?
