* Every sentence has two main parts: a simple subject and a simple predicate.

The simple subject of a sentence is the main word in the complete subject. It is always a noun or a pronoun. Sometimes, the simple subject is also the complete subject.

Example: Most birds | can fly.

Example: They | can fly because they have wings.

The simple predicate is the complete verb within the complete predicate. The simple predicate may be one or more words.

Example: Most birds | can fly.

Example: They | can fly because they have wings.

* Every sentence has two main parts: a complete subject and a complete predicate.

The complete subject includes all words that tell who or what the subject is.

Example: Most birds | can fly.

The complete predicate includes all words that state the action or condition of the subject.

Example: Most birds | can fly.

* An incomplete sentence is called a sentence fragment. A fragment lacks either a subject, a predicate, or does not communicate a complete thought. Here are some examples of sentence fragments:

Example: Saw that it was time to leave. à  lacks a subject

Example: The king and all his men. à  lacks a predicate

Example: Before we went to soccer practice. à  does not communicate a complete thought
