📚 Part 1: Comma Rules with Subordinating Conjunctions

Rule: When a subordinate clause (dependent clause) comes before the main clause, use a comma to separate them. When the subordinate clause comes after the main clause, usually no comma is needed.

Examples:

• Because it was raining, we stayed inside. (comma needed)

• We stayed inside because it was raining. (no comma needed)

Common subordinating conjunctions: because, although, since, when, while, if, unless, after, before, until
