A sentence fragment is part of a sentence that is punctuated as if it were a complete sentence.
To have a complete sentence you need three things:
1. The subject of the sentence (who or what is the sentence about)
2. A verb (an action done by or to the subject)
3. The sentence must express a complete thought
Let’s look at the following examples:
1. Fragment: Encouraging fitness and wellbeing.
2. Problem: There is no subject in this sentence.The sentence does not tell you who or what is encouraging fitness and wellbeing.
3. Corrected: The advertisement was encouraging fitness and wellbeing.
1. Fragment: My dog Ali.
2. Problem: There is no verb in the sentence. The reader does not know what the dog is doing.
3. Corrected: My dog Ali eats meat.
1. Fragment: Before I eat breakfast.
2. Problem: This fragmented sentence does not express a complete thought because it leaves you asking, in this case, what happens before I eat breakfast?
3. Corrected: Before I eat breakfast, I go for a walk.
