Complex Sentences

So we can fully understand what complex sentences are, we need to understand two important concepts:

  • A dependent clause is a group of words that has both a subject and a verb but cannot stand alone as a sentence. For Example: Where there is smoke
  • An Independent Clause is a group of words made up of a subject and a predicate, it can stand alone as a sentence. For example. I have to buy food from the Supermarket

Now we understand what dependent and independent clauses are , we can define what a complex sentence is

In grammar, Complex Sentences is a sentence with one independent clause and at least one dependent clause.

A complex sentence is often used to make clear which ideas are most important, and which ideas are subordinate.

Complex Sentences and Subordinating Conjunctions

The subordinate conjunction has two jobs.:

  • First, it provides a necessary transition between the two ideas in the sentence
  • The second job of the subordinate conjunction is to reduce the importance of one clause so that a reader understands which of the two ideas is more important.

Subordinating Conjunctions

Complex sentences are often formed by putting these words at the beginning of the dependent clause.

afteronceuntil
althoughprovided thatwhen
asrather thanwhenever
becausesincewhere
beforeso thatwhereas
even ifthanwherever
even thoughthatwhether

Differences Between Compound and Complex Sentences

One of the main differences between compound and complex sentences is that a compound sentence is made up of two independent clauses and a complex sentence is made of a dependent and independent clause

  • I usually play soccer and my brother plays basketball ( Compound Sentence)
  • I usually play soccer in the yard while my brother is watching TV (Complex Sentence)

As you can see in the examples, I usually play soccer, my brother plays basketball and I usually play soccer in the yard are independent clauses because they can stand on their own.

While my brother is watching TV is a dependent clause because it can’t stand on their own.
