Do you use commas around as well in the middle of sentence?

You don't typically use commas around "as well" in the middle of a sentence.

Here's why:

* "As well" is an adverbial phrase meaning "also" or "in addition."

* Adverbial phrases usually don't require commas unless they are interrupting the flow of the sentence.

Examples:

* Correct: I went to the store, and I bought milk as well. (The comma is used because of the conjunction "and".)

* Correct: I went to the store and bought milk as well. (No comma needed.)

* Correct: I bought milk, as well as eggs. (Comma is used because "as well as" is interrupting the sentence structure.)

Important Note: The placement of commas can be tricky. If you're unsure, it's always best to consult a style guide or grammar resource.
