Commas

Commas Joining Independent Clauses

Use a comma + coordinating conjunction (for, and, nor, but, or, yet, so — FANBOYS) to join two independent clauses: "She studied hard, and she passed." Without the conjunction, a comma alone creates a comma splice error: "She studied hard, she passed." ✗ — use a period, semicolon, or add a conjunction. A comma splice is one of the most common writing errors.
