I am trying to find the name for the rather recent, I think, rhetorical device of one-word sentences used for emphasis and effect.
Columnist Ruth Marcus, writing for the Washington Post, wrote this of Hillary Clinton's speaking fees:
“You don’t need any more! Just. Stop. Speaking. For. Pay.”
Columnist Michael Barone, writing in the Washington Examiner, wrote this about the chances of a contested Republican convention:
“I have bad news for those looking forward to a brokered convention. It. Isn’t. Going. To. Happen.”
Final example: Bob asks, "Are you ever going to stop using sentence fragments in your writing?"
Mary responds, "I. Don't. Think. So."
So, in the realm of rhetorical devices . . .
Repetition of a beginning word, phrase, or clause in consecutive sentences = Anaphora.
Insertion of conjunctions between every item in a series = Polysyndeton.
One. Word. Sentences. = ? ? ?
Can anyone help?
Footnote for anyone reading. From the related question, in terms of a search for the origin, really the best possibility which came to the fore was: https://en.wikipedia.org/wiki/Comic_book_guy. Possibly 1997. But the origin is still totally unclear, unfortunately; CBG could have been referring to something from the 80s, say.
