Exceptional Sentence Fragment Checker for Students and Writers

Sentence Fragment Overview

Sentence fragments are a mistake that students and writers frequently make. A sentence fragment checker is a useful writing tool for identifying and correcting sentence fragments. Sentence fragments are incomplete sentences. They lack at least one of the 3 essential elements that it takes to make a complete sentence. These elements are:

  • Subject. This is the person or thing that performs the action in a sentence. This is usually a noun, a noun phrase or a pronoun
  • Verb. The action being performed in the sentence.
  • Express a complete thought. The sentence must express a complete thought so the reader knows what it’s about.

When a phrase is missing any one of these elements it is an incomplete sentence. The following are some basic examples of sentence fragments:


  1. Sentence fragment 1: “Hiking in the mountains every weekend.” This is a sentence fragment because it has no subject. We don’t know who or what is hiking in the mountains.
  2. Sentence fragment 2: “My dog Spot.” This is a sentence fragment because it lacks a verb. We don’t know what Spot did.
  3. Sentence fragment 3: “For example, cake and ice cream.” This is an incomplete sentence because it doesn’t express a complete thought. The reader doesn’t know what cake and ice cream is an example of.

It isn’t always easy to spot sentence fragments, especially in your own writing. If you are having problems identifying sentence fragments in your writing you may want to consider using an incomplete sentence checker to assist you.

How to Identify Sentence Fragments

There are a number of different things you can look for in order to detect sentence fragments. Here is a list of some of the things you can check for:

  • Missing subject: sometimes known as lonely verb fragmented sentences, they can be identified because there is no subject in the phrase.
    • Example: “Ran across the road.”
  • Missing verb: if a phrase has no verb to communicate the action in a sentence it is a fragment
    • Example: “The boy across the river.”
  • Participle phrases: these are typically phrases that begin with a verb that ends in “-ed” or “-ing”. Participle phrases often fail to express a complete thought.
    • Example: “Holding a bag of groceries in each arm.”
  • Subordinate clauses: subordinate clauses, sometimes known as dependent clauses, are sentence fragments because they don’t express a complete thought. They require an independent clause to give them meaning.
    • Example: “Because the movie didn’t start until 10 pm.”
  • Appositives: an appositive is a noun phrase that clarifies and renames another noun. Appositives are often long and mistaken for complete sentences but on their own they are fragments.
    • Example: “The man who forgot his wallet every time it was his turn to pay the bill.”

Before you can begin repairing sentence fragments you have to identify them which can be confusing and difficult for some. A good sentence fragment identifier can remove some of the confusion from the process.

How to Correct a Sentence Fragment

There are a number of different ways you can correct a sentence fragment. The key is to repair the sentence fragment by making it a complete sentence. The following are some examples of sentence fragments and corrections that can be made so that they are complete sentences:

  • Add a subject: a sentence fragment missing the person or thing performing an action can be fixed by adding a subject.
    • Sentence fragment: “Ran to the store to get ingredients for an apple pie.”
    • Corrected version: “David ran to the store to get ingredients for an apple pie.”
  • Add a verb: when a phrase is missing an action add a verb to make it a complete sentence.
    • Sentence fragment: “The injured man down the mountain trail.”
    • Corrected version: “The injured man limped down the mountain trail.”
  • Add an independent clause to a subordinate clause: a subordinate clause can’t stand on its own and be understood. It must be combined with an independent clause in order to know what is happening.
    • Sentence fragment: “Since it was the weekend.”
    • Corrected version: “Since it was the weekend, George decided to sleep in late.”
  • Attach the appositive to a main clause: attaching an appositive to a main clause is one way of turning it from a fragment into a complete sentence. Always use commas to attach the appositive whether it comes at the beginning, middle or end of a sentence.
    • Sentence fragment: “The girl who played the piano so beautifully.”
    • Corrected version: “Susan, the girl who played the piano so beautifully, held the audience entranced until the last note.”
  • Add an independent phrase to a participle phrase: similar to a subordinate clause, a participle phrase doesn’t express a complete thought and requires an independent clause to be understood.
    • Sentence fragment: “Moving the heavy boxes to his new second-floor apartment.”
    • Corrected version: “Joe hurt his back last week moving the heavy boxes to his new second-floor apartment.”
