Dear Sunshine: I'm an ignorant old Yankee, and in New England, the old timers frequent used "eh" as an interrogoative expletive. I don't know proper terminology, but it would be sort of a brief "schwa" coming from deep in the throat. " Eh, what's that you said?" My dictionary gives is as a long A. In old time New England, agreement might start with "Ayuh" When I was in the South, the natives used to fall down laughing. "Did you hear him say 'Rownd abowt and owt in the boooshes?"
