Do you put a comma after yes when starting sentence?

Yes, you do put a comma after "yes" when it starts a sentence.

This is because "yes" is an interjection in this case, and interjections usually require a comma after them.

Here are some examples:

* Yes, I would love to go to the movies with you.

* Yes, please, I'll have the soup and salad.

* Yes, but I have a meeting later this afternoon.
