Tips to avoid writing incomplete sentences

Sentence Fragments are incomplete statements that are presented as a full sentence. We often use sentence fragments conversationally when speaking, but it is important to avoid fragments when writing academic papers to maintain a formal tone.

Sentence fragments occur when a sentence does not feature a subject or verb. Beginning a sentence with a subordinating word can also produce a fragment. Take a look at these examples: 

 

No Subject 

  • Fragment: Went to the store and didn’t buy anything.  

    • Who went to the store? To fix this sentence fragment, add a clear subject.  

  • Full sentence: I went to the store and didn’t buy anything. (A clear subject, “I”, is added to the sentence) 

 

No Verb 

  • Fragment: Wuthering Heights by Emily Brontë, a book with great emotion.  

    • This fragment has no verb. To fix this fragment, remove the comma and add a verb.  

  • Full sentence:  Wuthering Heights by Emily Brontë is a book with great emotion. 

 

Sentence begins with a Subordinating Word  

  • Subordinating words include: after, although, because, since, until, when, where, while, which 

  • Fragment: Although I missed the bus.  

    • This fragment begins with the subordinating word “Although.” To fix this fragment, either remove the subordinating word or change the structure of the sentence.   

  • Full sentence:  I missed the bus. (Subordinating word is deleted) 

  • Full sentence: Although I missed the bus, I still arrived on time. (Additional explanation is added to complete the sentence)
