Do You use a comma to set off direct address in sentence?

Yes, you use a comma to set off direct address in a sentence.

Direct address is when you are speaking directly to someone or something.

Here are some examples:

* "John, can you pass the salt?" (John is being directly addressed)

* "Please, Mom, can I stay up late tonight?" (Mom is being directly addressed)

* "Hey, Google, what's the weather today?" (Google is being directly addressed)

Note:

* The direct address is always separated from the rest of the sentence with commas.

* If the direct address is at the beginning of the sentence, the comma goes after it.

* If the direct address is at the end of the sentence, the comma goes before it.
