Do you need a comma before the word then?

You don't *always* need a comma before "then," but it often depends on the context and the type of sentence. Here's a breakdown:

When you DO need a comma before "then":

* After a dependent clause: If "then" follows a dependent clause (a clause that can't stand alone as a sentence), you generally need a comma.

* Example: *After I finished my homework, then I went to bed.*

* For clarity in complex sentences: If you have a long or complex sentence, a comma before "then" can help separate the ideas and improve readability.

* Example: *The meeting was scheduled for 10 am, but the CEO was delayed, so we had to wait, then we finally got started.*

When you DON'T need a comma before "then":

* After an independent clause: If "then" follows a complete sentence, you typically don't need a comma.

* Example: *I finished my homework, then I went to bed.* (The phrase "I finished my homework" is a complete sentence.)

* In simple, short sentences: In very short and straightforward sentences, the comma might be unnecessary.

* Example: *I ate breakfast then I went to work.*

Important note: These are general guidelines. There are always exceptions, and context is crucial. If you're unsure, it's always best to err on the side of using a comma.

Ultimately, the best way to determine whether a comma is needed is to read the sentence aloud and see if it sounds natural and clear.
