In the past few years I've noticed people answering questions they just asked themselves.
Instead of saying, "I think the Dallas Cowboys will reach the playoffs but not make it to the Super Bowl", they might say, "Do I think the Cowboys will make the playoffs? Sure. But do I think they will make it to the Super Bowl? No way."
I hear this every day, especially from the talking heads on television. It seems strange to hear someone carry on a one-person dialog in the middle of a conversation.
Is this a recent style of speaking or am I just focusing on a new pet peeve? And is is there a name for this?
Being non-native English speaker, I hear it for the first time. Perhaps it's a way of emphasizing the key points in conversation. Â
What should I call this practice? Anthypophora. Is it new? Not on your life. Is it a recent fad? Almost certainly. Are there other words for it? You bet:
antipophora
antihypophora
hypophora
subjectio
rogatio
contradictio
figure of response
It is as old as anything, and the contexts are as often serious as not, often a public person explaining a viewpoint to a crowd. Wiki points to way back:
The rhetorical effectiveness lies in allowing the speaker to answer questions the listener may have. For instance, in  Paul's  Epistle to the Romans, Paul is explaining  Jesus  and he says "Is He  the God of the Jews only?  Is He  not also of the Gentiles? Yes, of the Gentiles also" (Romans 3.29). In this manner, Paul confirms to the reader that God is god of both the Jews and Gentiles.
I've looked this up before with no success, thanks for all the information!
