Do you put a comma before even though?

You don't put a comma before "even though" unless it's introducing a dependent clause that comes before the independent clause.

Here's how to understand it:

1. Dependent clause before independent clause:

* Example: "Even though it was raining, we decided to go for a walk."

* Explanation: "Even though it was raining" is a dependent clause because it can't stand alone as a complete sentence. The independent clause is "we decided to go for a walk." You need a comma here because the dependent clause comes first.

2. Independent clause before dependent clause:

* Example: "We decided to go for a walk, even though it was raining."

* Explanation: "We decided to go for a walk" is a complete sentence (independent clause). "Even though it was raining" is a dependent clause. You don't need a comma here.

In short:

* Comma before "even though" when it introduces the clause: Even though...

* No comma before "even though" when it's within the clause: ...even though...
