Common Sentence Fragments Mistakes and How to Avoid Them
The most frequent sentence fragments errors writers make and how to catch them.
Where writers actually slip up
Most sentence fragment mistakes cluster into a few familiar traps. Knowing them ahead of time is far easier than discovering them in a marked-up draft.
A sentence fragment is a group of words punctuated as a sentence but missing a subject, a verb, or a complete thought. Because it was raining is a fragment.
Here are the errors that show up again and again, with the fix for each one.
Subordinating words like although, because, and since are the most common fragment starters, so check any sentence that begins with one.
A fragment is not the same as a short sentence, since a short complete sentence still has a subject and a verb.
If a fragment reads well as a stylistic choice in fiction or ads, keep it, but in formal writing attach it to a main clause.
A fragment attached to the sentence before it usually solves the problem without changing meaning.
The mistakes that repeat most
- Leaving a because clause on its own: Because the deadline was tight.
- Treating a list or phrase as a full sentence.
- Starting a sentence with a transition and stopping short.
- Confusing a long fragment with a complete sentence just because it sounds long.
Mistake, cause, and fix
| Common mistake | Why it happens | How to avoid it |
|---|---|---|
| Leaving a because clause on its own: Because the deadline was tight | Habit or inattention while drafting. | Slow down and check on an editing pass. |
| Treating a list or phrase as a full sentence | Habit or inattention while drafting. | Slow down and check on an editing pass. |
| Starting a sentence with a transition and stopping short | Habit or inattention while drafting. | Slow down and check on an editing pass. |
| Confusing a long fragment with a complete sentence just because it sounds long | Habit or inattention while drafting. | Slow down and check on an editing pass. |
When you write fast, your ear fills in what should be there instead of what is. A separate editing pass is where these mistakes get caught.
Catching mistakes before they ship
