A sentence fragment is an incomplete sentence that lacks either a subject, predicate, or does not communicate a complete thought. Examples of fragments include "Saw that it was time to leave" which lacks a subject and "The king and all his men" which lacks a predicate. Dependent clauses like "Before the test began" and "As soon as you get home" are also fragments because a clause cannot stand alone as a sentence. To fix fragments, an independent clause must be added to form a complete sentence.
