What do you call a period or comma question mark?

You can't call a period, comma, or question mark by a single name because they are all distinct punctuation marks with different functions.

Here's a breakdown:

* Period (.) Indicates the end of a sentence.

* Comma (,) Used to separate items in a list, clauses in a sentence, or to indicate a pause.

* Question mark (?) Indicates a question.
