Armed with knowledge about phrases and clauses, you are ready to edit for sentence structure. Let’s start by looking at fragments, errors that result in lower grades and cause teachers and bosses to pull out their hair.

Sentence structure problem #1: Fragments

So what exactly is a fragment? The word itself tells you that it’s a piece of something; in this case, it is a piece of a sentence. A fragment is an incomplete sentence because (1) it lacks a subject, or (2) it lacks a verb or part of a verb, or (3) it is a subordinate clause. A fragment is a phrase or a subordinate clause pretending to be a sentence.

Now that you’re sure what sentence fragments are, let’s consider how to fix them. The simplest fixes involve zeroing in on what is missing.

If a fragment is missing a subject, add a subject.

If a fragment is missing a verb or part of the verb phrase, add it.

If a fragment is a subordinate clause, attach it to a nearby independent clause. That independent clause could be the sentence before or after the subordinate clause—or you could add a new independent clause to make the sentence complete.

If a fragment is a prepositional phrase, add whatever it needs to make it a complete sentence.
