How can we best describe the meaning of this phrase to a non-native English speaker?
Example Dialogs:
Sally: Isn’t Twilight the best movie series of all time?
Fred: Yeah, no.
Fred: Doesn’t it bother you that vampires sparkle?
Sally: Yeah, no, not really.
One way of thinking of the response “Yeah, no” is that the first part (“yeah” or an affirmative) acknowledges the question and the second part (“no,” “naw,” or negative) refutes what the question is implying. Thus:
S: Isn’t twilight the best movie series of all time?
F: Yeah, I see why you would think that. But no, I don’t agree with you.
