A comma splice occurs when two independent clauses are connected with only a comma. To identify a comma splice, look for two complete sentences joined together with a comma without a coordinating conjunction (and, but, or, etc.) or a semicolon. Fix a comma splice by adding a coordinating conjunction, replacing the comma with a semicolon, or using a period to make separate sentences.
