When do you put a comma before because?

Answer 1

You use a comma with because when you are using it as the beginning of a dependent clause or modifying clause. For example

Because Latoya was allergic to shrimp, Laquetta opted to make steak for the dinner party.

or

Uncle Joe, because of his demetia, accidentally confused me with the grim reaper, subsequently opting to throw a bag of potato chips at my head.

BECAUSE IS NOT A CONJUCTION...CONSEQUENTLY IT SHOULD NEVER BE USED AS ONE. THESE ARE THE TWO GENERALLY ACCEPTED USES FOR COMMAS AND BECAUSE.

In fact, it's easier to just remember that you NEVER use a comma before the word "because". In the example above, the comma follows the dependent clause. It does not precede it and never should. "Because" ALWAYS introduces a dependent clause and should NEVER have a comma before it. Here's the rule: Independent clause + dependent clause = no comma.

Dependent clause + independent clause = comma AFTER the dependent clause.

Answer 2

A comma is typically used before "because" when it joins two independent clauses in a sentence. For example: "I went to the store, because I needed to buy some groceries."
