Simple Compound and Complex Sentences: Overview

Before we start with the simple, compound and complex sentences worksheet, it is time we run through the basics of all these three types of sentences and how each type of sentence is used and formed.

Simple Sentences

As the name suggests, a simple sentence is very basic consisting of of a subject and a predicate. It is a sentence that contains only one independent clause. An independent clause is a group of words that can stand alone as a complete sentence. It must have a subject and a verb.   

Example:

“The cat sat on the mat.”

In this sentence:

• “The cat” is the subject.
• “sat” is the verb.

Compound Sentences

A compound sentence is a sentence that connects two independent clauses, typically with a coordinating conjunction like “and” or “but.”   

Complex Sentences

A complex sentence is a sentence that contains one independent clause and at least one dependent clause.  

Example:

“Although I was tired, I finished my homework.”

Here, “I finished my homework” is the independent clause, and “Although I was tired” is the dependent clause.
