GRAMMAR FOR WRITING
Complex Sentences
In Unit 10,you learned how to write longer compound sentences by connecting two simple
sentences with a connector called a coordinating conjunction (and,but,plex sentences
are another type of longer sentence.
A complex sentence consists of two clauses:an independent clause and a dependent clause.
A clause is a group of words that includes a subject and a verb.
INDEPENDENT CLAUSE
DEPENDENT CLAUSE
S V
Reem studied all weekend
because she had a test on Monday.
An independent clause can be a sentence by itself.A dependent clause cannot be a sentence;it
needs the independent clause to make sense.A dependent clause by itself is called a fragment.
The words because,after,before,when,and ifare common connectors used in complex sentences.
They are called subordinating conjunctions.They go at the beginning of the dependent clause.
