written expression

Good writing is made up of clear, grammatical sentences. You can take a step toward writing good sentences by understanding their structure.

A sentence is a group of words that contain a subject and a predicate. It expresses a complete thought and is not dependent on another group of words to complete its meaning.

The subject is the noun or pronoun that names who or what the sentence is about. The predicate is the verb and its objects, complements, and modifiers.
