Sentence Fragments: Identifying and Correcting Common Errors in Writing
Introduction:
In written communication, a sentence fragment occurs when a group of words is punctuated as a complete sentence but lacks one or more essential components, such as a subject, a predicate, or a complete thought. Sentence fragments can create confusion, disrupt the flow of writing, and negatively affect readability. Recognizing and correcting sentence fragments is essential for clear, concise, and effective communication, especially in academic and professional writing.
This module will guide you through the process of identifying sentence fragments, understanding the rules for constructing complete sentences, and applying strategies to fix common errors. By the end of this study module, you will be able to confidently spot and correct sentence fragments in your writing.

1. What Are Sentence Fragments?
Definition and Importance
A sentence fragment is a group of words that appears to be a sentence but is incomplete. It either lacks a subject, a predicate, or both, making it grammatically incorrect. In formal writing, sentence fragments are considered errors because they hinder understanding and clarity.
Components of a Complete Sentence
For a sentence to be complete, it must have:
- A subject (the person, place, thing, or idea the sentence is about).
- A predicate (what the subject is doing or the state of being).
- A complete thought (the sentence should express a full idea and not leave the reader wondering about additional information).
Common Causes of Sentence Fragments
- Missing a subject: “Running through the park.”
- Missing a predicate: “The dog in the yard.”
- Dependent clauses used without a main clause: “Although I tried to study.”
2. Types of Sentence Fragments
Missing Subject
A sentence fragment may occur when a subject is missing, leaving the reader uncertain about who or what is being discussed.
- Example: “Jumping over the fence.”
- Corrected: “He is jumping over the fence.”
Missing Predicate
When the verb or the predicate is missing, the sentence lacks an essential component that describes the action or state of being.
- Example: “The man in the suit.”
- Corrected: “The man in the suit is talking to the manager.”
Dependent Clause Fragments
A dependent clause cannot stand alone as a sentence because it does not express a complete thought.
- Example: “Although it was raining.”
- Corrected: “Although it was raining, we decided to go for a walk.”
Fragmented Prepositional Phrases
A prepositional phrase, when used alone, cannot form a complete sentence.
- Example: “On the table.”
- Corrected: “The book is on the table.”
Fragments After Coordinating Conjunctions
Using conjunctions (and, but, or, so, for) to start a sentence without a complete thought can create a fragment.
- Example: “He wanted to leave, but.”
- Corrected: “He wanted to leave, but he was too tired.”
3. How to Identify Sentence Fragments
Analyzing Sentence Structure
Check if the sentence has both a subject and a predicate. If either one is missing, the sentence may be a fragment.
Recognizing Incomplete Thoughts
Ask yourself if the sentence expresses a complete idea. If the sentence leaves you wondering, it is likely a fragment.
Testing for Subject-Verb Agreement
Ensure that the subject and verb agree in number and person. Incomplete or incorrect subject-verb pairs often lead to fragments.
4. How to Correct Sentence Fragments
Adding Missing Elements
To fix a fragment, you can add the missing subject or predicate to complete the thought.
- Example: “While shopping at the store.” → “While shopping at the store, I saw my friend.”
Combining Fragments with Complete Sentences
If a fragment is connected to a complete sentence, you can combine them to form a correct sentence.
- Example: “He was late. Because of the traffic.” → “He was late because of the traffic.”
Using Punctuation and Conjunctions Correctly
Fragments that result from conjunctions can be corrected by using proper punctuation or conjunctions to connect them to complete thoughts.
- Example: “She studied all night. But she was still tired.” → “She studied all night, but she was still tired.”
