Your mention of "aunt" here -- I discovered recently, to my surprise, that the majority of Americans (if they're not from Boston
), pronounce this word "ant", like the insect. I'd just taken it for granted that everyone pronounced it "ahnt", the same way as myself and, I think, everyone I know. Not so, I find; and moreover, apparently often people in the north of England also say it as "ant" (I'm middle-class southern).
Re the word's general American pronunciation here: learning of it has, at least, shed light for me on a little verse by Ogden Nash which I discovered in childhood, and long just thought of as a bit of random silliness on the part of that comic-verse exponent:
"The anteater
Is an uncle-beater.
On the other hand, the skunk'll
Beat his aunt and eat his uncle."
I now get the pun with the third word of the final line, which previously I didn't.
