Commas With Coordinating Conjunctions

Captions available

The idea

Use a comma before a coordinating conjunction that joins two independent clauses.

In practice

"Businesses are growing, and unemployment is down." Each side has a subject and a verb, so the comma goes before and.

Where people slip

Without the conjunction, the comma alone makes a comma splice, and without the comma, long clauses can run together.
