Where do you put a comma when using the word therefore in sentence?

"Therefore" is usually treated as a conjunctive adverb, which means it connects two independent clauses.

Here's where you put the comma when using "therefore":

1. Before "therefore": Place a comma before "therefore" when it connects two independent clauses.

* Example: The weather was terrible, therefore, we decided to stay home.

2. After "therefore": Place a comma after "therefore" only if the second clause is a dependent clause.

* Example: We decided to stay home, therefore, we wouldn't have to worry about getting caught in the storm.

Important Note: "Therefore" can also be used within a sentence without any commas if it is not connecting independent clauses.

* Example: We decided to stay home because of the terrible weather; therefore, we watched a movie.
