What is a sentence fragment?

a sentence that doesn't contain all of the necessary parts of speech to be a complete sentence.

Ex: was running down the street.( missing subject at beginning of sentence.)

Correct way: The man was was running down the street.

A helpful hint is if it doesn't sound right when you say it look to see if it is missing anything.

A sentence fragment is simply an incomplete sentence. It can be a sentence missing a main subject or main verb, or it can be a disjointed dependent clause.

Example: This not sentence.

A sentence without both a subject and predicate(where the verb is). A sentence fragment basically has one or the other.

Exs:

Subject only:

The cat.

Predicate only:

Walks many miles.
