A sentence fragment is a group of words punctuated like a sentence but missing a subject, a verb, or a complete thought. “Because it was raining.” is a fragment — it needs a main clause to finish the idea. Paste your own sentence into the free checker below to fix it in one click.

## How it works

1. **Spot the pattern** — Check that the words can stand alone. Watch openers like “Because”, “Although”, “Which”, and “-ing” phrases — they often introduce a clause that never connects to a main one.
2. **Apply the rule** — Attach the fragment to a nearby main clause, or add the missing subject or verb. “Because it was raining” becomes “We stayed inside because it was raining.”
3. **Check your sentence** — Paste your text into the grammar checker below — it flags the issue and shows the correction.
4. **Re-read it** — Read the corrected version aloud to confirm it says exactly what you meant.

## The rule

A complete sentence needs a subject, a verb, and a complete thought. If any of the three is missing, it’s a fragment — even if it starts with a capital and ends with a period.

## How to spot it

Check that the words can stand alone. Watch openers like “Because”, “Although”, “Which”, and “-ing” phrases — they often introduce a clause that never connects to a main one.

## How to fix it

Attach the fragment to a nearby main clause, or add the missing subject or verb. “Because it was raining” becomes “We stayed inside because it was raining.”

## The most common mistake

Treating a subordinate clause (“Although she tried hard.”) as a full sentence. It needs a main clause to complete the thought. If you’re not sure whether your sentence has the problem, paste it into the checker above — it catches this and explains the fix in plain language.

**Before → after**

| ❌ Incorrect | ✓ Corrected | Why |
| --- | --- | --- |
| Because it was raining. | We stayed inside because it was raining. | Added a main clause |
| Running down the street. | A dog was running down the street. | Added a subject and verb |
| Which was the best part. | The ending, which was the best part, surprised everyone. | Connected to a main clause |

## FAQ

**What is a sentence fragment?**

An incomplete sentence missing a subject, a verb, or a complete thought — for example, “After the long meeting.” It needs to be completed or joined to a full clause.

**Are fragments ever okay?**

In fiction, ads, and casual writing, fragments are used for effect (“Not anymore.”). In academic and professional writing, treat them as errors to fix.

**How do I check my own writing for this?**

Paste your text into the free grammar checker on this page. It flags the issue, suggests a correction, and explains why — so you learn the rule, not just the fix.

**Is it free?**

Yes — your first run needs no account, and a free account adds 5 more, each up to 1,500 words. They are a one-time grant, not a daily allowance. Upgrade for a word pool that removes the per-run cap, or use the free iOS app.
