Sentence vs fragment
A complete sentence is the basic building block of all writing, but not every group of words is a sentence. A fragment looks like a sentence and may even sound like one, but it is missing something essential. Knowing the difference — and knowing how to fix a fragment — makes writing clearer and easier to read.
- What makes a group of words a complete sentence
- How to spot a fragment by checking for a subject, a verb and a complete idea
- Three reliable methods for fixing a fragment
- Sentence — a group of words that has a subject, a verb and expresses a complete idea. For example, The student asked for help is a complete sentence.
- Fragment — a group of words that is missing a subject, a verb, or a complete idea. For example, Asked for help has no subject.
- Subject — the person or thing doing the action in the sentence. For example, in Liam raised his hand, Liam is the subject.
- Verb — the action or state word in the sentence. For example, in She waited quietly, waited is the verb.
- Complete idea — the sentence must make sense on its own. For example, Because he was confused is not complete — the reader expects more.
How it works
1Checking for a complete sentence
Every complete sentence passes three checks: it has a subject, a verb and a complete idea. Running through these three checks is the fastest way to decide whether a group of words is a sentence or a fragment.
- Subject check — ask who or what is doing something. For example, in The class listened carefully, The class is the subject.
- Verb check — ask what is happening or what is the state. For example, listened is the verb in that same sentence.
- Complete idea check — read the words and ask if the thought is finished. For example, When the teacher arrived leaves the reader waiting — it is a fragment.
2Spotting common fragment types
Most fragments fall into one of three types. Recognising the type helps the writer choose the right fix.
- No subject — the fragment has a verb but no one doing it. For example, Ran to the oval after lunch — who ran? The subject is missing.
- No verb — the fragment names something but no action or state is given. For example, The student with the red bag — what did the student do?
- Incomplete idea — the fragment starts with a connecting word like because, when or although and leaves the main point unfinished. For example, Because she forgot her question.
3Three ways to fix a fragment
Once a fragment is identified, it can be fixed in three ways. Choosing the best method depends on what is missing.
- Add the missing part — add a subject or verb to complete the fragment. For example, Ran to the oval after lunch becomes Liam ran to the oval after lunch.
- Join to a nearby sentence — attach the fragment to the sentence before or after it. For example, She forgot her question. Because she was nervous. becomes She forgot her question because she was nervous.
- Rewrite as a full sentence — reword the fragment so it has a subject, a verb and a complete idea. For example, The student with the red bag becomes The student with the red bag raised her hand.
See it in action
Fragment with no subject
Ran to the oval after lunch.
Liam ran to the oval after lunch.
Adding Liam as the subject tells the reader who performed the action, completing the sentence.
Fragment with no verb
The student with the red bag.
The student with the red bag raised her hand.
Adding the verb raised and the rest of the idea turns the fragment into a complete sentence.
Fragment starting with 'because'
She forgot her question. Because she was nervous.
She forgot her question because she was nervous.
Joining the fragment to the sentence before it removes the incomplete idea and creates one clear, complete sentence.
- A complete sentence needs a subject, a verb and a complete idea.
- A fragment is missing at least one of these three things.
- The three most common fragment types are: no subject, no verb, and incomplete idea.
- Fix a fragment by adding the missing part, joining it to a nearby sentence, or rewriting it as a full sentence.
- Always read sentences aloud — if a thought feels unfinished, it is likely a fragment.
- sentence(n.) a group of words with a subject, a verb and a complete idea — The class asked a question is a complete sentence.
- fragment(n.) a group of words that is missing a subject, a verb, or a complete idea — Because she was nervous is a fragment.
- subject(n.) the noun or pronoun that performs the action in a sentence — in Maya raised her hand, Maya is the subject.
- verb(n.) the word that expresses the action or state in a sentence — in The student waited, waited is the verb.
