What is an Adverb Clause?
Adverb clauses are clauses that function as adverbs.
Since they are dependent clauses, they must have a
subordinating conjunction to connect them to the other
clause.
Subordinating conjunctions can be arranged according
to the purpose of the clause they begin. Here are some
examples of subordinating conjunctions:
Time Clauses
(She went to Palestine before she came to the U.S.
Reason Clause ( She went to Palestine first because
she couldn’t get a visa for the U.S.
Purpose Clause (She came to the U.S. so that she
could be with her relatives
Contrast Clause (She came to the U.S. even though
she didn’t know English.
Condition Clause (She will go back to her country if
she saves enough money.
