Which term describes two sentences joined incorrectly with only a comma?

• A. Fragment
• B. Comma splice
• C. Run-on
• D. Subject-verb agreement

Answer: (B)

Two independent sentences joined by only a comma create a comma splice, a punctuation error. An independent clause has both a subject and a verb and can stand on its own, so linking two of them with just a comma doesn’t provide a strong enough connection. To fix it, use a semicolon, a period, or add a coordinating conjunction after the comma (for, and, but, or, nor, yet, so). For example: “She finished the project, and she submitted it” or “She finished the project; she submitted it” or “She finished the project. She submitted it.” This distinguishes it from a fragment (an incomplete sentence) or a subject-verb agreement issue, and it also differs from a run-on, which would lack proper punctuation between the independent clauses.
