Comma splice

A comma splice is a punctuation error. Two complete sentences, each able to stand alone, are joined with only a comma, as in it was late, we went home. A comma is not strong enough to link two main clauses on its own.

You can fix the fault in several ways. Use a full stop, add a connective such as and or but after the comma, use a semicolon, or make one clause subordinate. Recognising and correcting comma splices is important for writing accurate, well-punctuated sentences.

In every writing task, comma splices are a common accuracy error that examiners notice. Repeated splices lower your marks for technical control. Learn to spot two complete clauses joined by only a comma, and fix the join correctly.

This is a quick way to raise the accuracy of your writing. It also deepens your understanding of sentence structure, since fixing a splice means recognising main clauses.

The bell rang, the students left is a comma splice. It becomes correct as The bell rang, and the students left or The bell rang; the students left.

When proofreading, check each comma to see whether it joins two complete sentences. If it does, fix the join with a full stop, a connective, a semicolon, or by making one clause subordinate. In your own writing, be especially alert to this in longer passages.

Understanding the comma splice reinforces your grasp of where one sentence really ends.
