Do you put a comma before the phrase as well when it falls at end of sentence?

You do not put a comma before the phrase "as well" when it falls at the end of a sentence.

Here's why:

* "As well" is an adverbial phrase that modifies the entire sentence. It adds information about the previous statement.

* Adverbial phrases at the end of a sentence are not usually separated by a comma.

Examples:

* Correct: I went to the store and bought groceries as well.

* Incorrect: I went to the store and bought groceries, as well.

However, there are some exceptions:

* If "as well" is used to connect two independent clauses, you would put a comma before it.

* If "as well" is used parenthetically, you would put commas before and after it.

Examples:

* Correct: I went to the store, and I bought groceries as well. (two independent clauses)

* Correct: I went to the store, as well as the bakery, and bought groceries. (parenthetical phrase)
