More on Sentences

A sentence is a word or group of words that expresses a complete thought. A simple sentence has two parts: the subject and the predicate.

The subject is the who or what we talk about in a sentence. The predicate is the part of the sentence without the subject.

52.1 Main and Dependent Clauses

A clause is a group of words that contains both a subject and a predicate and is part of a sentence. A sentence may have two or more clauses. For simplicity, we will only look at two-clause sentences.

ClauseClause
We were eating dinnerwhen the telephone rang.
I love the cookiesthat your mother made.

There are two kinds of clauses: main and dependent. A main clause expresses a complete thought and can stand alone as a sentence.

Main Clause
We were eating dinner.
I love the cookies.

A dependent clause does not express a complete thought and cannot stand alone. It depends on the main clause to complete its meaning.

Dependent Clause
when the telephone rang
that your mother made
