Sentence Fragment Checker
Find incomplete sentences and fix broken thoughts with our free sentence fragment checker. Make your writing clear and easy to understand
What Is a Sentence Fragment?
A sentence fragment is a group of words that looks like a sentence but does not express a complete thought. It may be missing a subject, a main verb, or an independent clause.
Consider this example:
Because I missed the morning bus.
Here is the complete version:
Because I missed the morning bus, I arrived late for class.

Fix All Types of Sentence Fragments
Dependent-Clause Fragments
A dependent clause begins with a word such as “because,” “although,” “when,” or “while.” It cannot usually stand alone.
Missing-Subject Fragments
Some fragments describe an action but never tell the reader who or what performs it.
Missing-Verb Fragments
A sentence needs a working verb. Without one, the reader receives a description—not a complete statement.
Phrase Fragments
A phrase may provide useful detail, but it cannot always carry a full idea by itself.
“-ing” Fragments
A word ending in “-ing” can create a fragment when it lacks a helping verb or a complete main clause.
Afterthought Fragments
Words such as “especially,” “including,” and “such as” can introduce details that become disconnected from the main sentence.
Added-Detail Fragments
An added-detail fragment gives extra information but cannot stand alone. It often begins with words such as “especially,” “including,” “except,” “such as,” or “for example.”
