Give 5 example of sentence fragment?

A sentence is a complete clause with a subject and a finite verb.

A sentence fragment is not a complete clause, but is part of a clause (often lacking the verb to make a full sentence). For instance, a sentence fragment could be:

The house that I used to live in.

Swimming in the river.

I cannot find. (missing the object, the 'what')

When he came home.

The business around the corner.

The cigarette in my hand.

As he kissed.

How did?

Many questions.

When she saw the spider.

NOTE: NONE of those should have periods because they are NOT complete sentences. MOST need a comma, and the rest of the sentence. A couple only need the rest of the 'complete thought', such as:

The cigarette in my hand was burning.

How did she know where I lived?

Many questions are difficult to answer.
