Ending a sentence with an abbreviation or initials
QuestionWhen a set of initials appear at the end of a question, does it look like this:
\"Who has the initials, D.S.?\"
Or like this:
\"Who has the initials, D.S?\"
Response
In a statement, when the period after an abbreviation (or initials, in this case) ends a sentence, you don't add another period to end the sentence. In a question (or with an exclamation), on the other hand, end the abbreviation, or initials, with its period and then add the appropriate end-mark. (I don't know why you'd want to put a comma in that sentence . . . )
