1. Complete Sentences VS Fragments

2. What is a complete sentence?
A complete sentence must have three things.
At least one subject
At least one verb
Express a complete thought
Example:
The referee blew his whistle after he saw the foul.

3. What is a fragment?
A fragment is when a sentence is missing at least one of those three things.
Sentence fragment that lacks a subject
Helped Jim wash the car.
Sentence fragment that lacks a verb or part of the verb
Jenny swimming in the lake.
Sentence fragment that lacks a complete thought
As long as you understand my problem.

4. Understood Subject
Do not confuse a sentence with an understood subject with an incomplete sentence.
An understood subject is when the subject of a request or command is not stated but understood to be “you.”
Put the dirty dishes in the sink = (You) put the dishes in the sink.
