Types of Sentences Grammar Lessons

By Jaime Austin

Lesson 1:​
Sentences and Sentence Fragments

​A sentence is a group of words that expresses a complete thought.
Each sentences has a subject part that names whom or what the sentence is about and a predicate part that tells what the subject does or has.
The predicate may also tell what the subject is or is like.

There are four types of sentences: declarative, interrogative, exclamatory, and imperative.

A sentence fragment is a group of words that lacks either a subject, a predicate, or both.
A fragment does not express a complete thought.

​Lesson 2:
Subjects and Predicates

The complete subject includes all the words in the subject.
The main word or group of words in the complete subject is called a simple subject.
A compound subject has two or more simple subjects with the same predicate (verb).
The complete predicate includes all the words in the predicate.
The main word or group of words in the complete predicate is called the simple predicate.
A compound predicate has two or more simple predicates with the same subject.

​Lesson 3:
Simple and Compound Sentences

​A simple sentence has one complete subject and one complete predicate. It may have a compound subject, compound predicate, or both.

A compound sentence contains two or more simple sentences joined by a comma and a coordinating conjunction or by a semicolon.

A run-on sentence is two or more sentences incorrectly written as one sentence. Correct a run-on sentence by rewriting it as two separate sentences or by joining the sentences with a semicolon or with a conjunction.
