Definitions of Simple, Compound and Complex Sentences

Simple Sentences

A simple sentence contains a single independent clause with a subject and a predicate. It expresses a complete thought and is straightforward.

Example:

• The cat sleeps.

• She enjoys reading books.

Compound Sentences

A compound sentence consists of two or more independent clauses joined by a coordinating conjunction (for, and, nor, but, or, yet, so) or a semicolon. Each clause can stand alone as a complete sentence.

Example:

• The cat sleeps, and the dog barks.

• She enjoys reading books, but he prefers watching movies.

Complex Sentences

A complex sentence contains one independent clause and at least one dependent (or subordinate) clause. The dependent clause provides additional information to the main clause and is connected by subordinating conjunctions (because, although, if, since, when, etc.).

Example:

• The cat sleeps because it is tired.

• She enjoys reading books when she has free time.

This recap should help clarify the differences and structures of each type of sentence.
