A comma splice is a grammatical error that occurs when two independent clauses are joined with only a comma. This can make your writing confusing and difficult to read. To avoid comma splices, you should use a semicolon, a coordinating conjunction (such as “and,” “but,” or “or”), or a subordinating conjunction (such as “because,” “although,” or “when”).
Avoiding comma splices is important for clear and effective writing. When you use a comma splice, you are essentially creating two sentences that are not connected. This can make your writing confusing and difficult to follow. In addition, comma splices can make your writing sound choppy and unprofessional.
