1. Sentence Fragments

2. Fragments are incomplete sentences
Fragments are incomplete sentences. Usually, fragments are pieces of sentences that have become disconnected from the main clause.
 The fragment is frequently a dependent clause or long phrase that follows the main clause.
Independent Clause vs. Dependent Clause
A sentence stands alone and makes sense, which is why we call a sentence an independent clause.
Clauses that lack either a subject or a verb (or both) depend on an independent clause to provide meaning; hence, they are referred to as dependent clauses.

5. How Do I Avoid Writing Fragments?
One of the easiest ways to correct them is to remove the period between the fragment and the main clause.
Other kinds of punctuation may be needed for the newly combined sentence.
