Here is a funny diversion for speakers of American English that might be a fun at your next dinner party. I chafe a bit at writing the oxymoronic misnomer, "American English," but when I took the quiz found on the page linked below, my geographic origins were pegged very precisely. Quite weird!
As an upstate New Yorker, educated in the Midwest, my quiz results identified me as 55% General American English, 15% Yankee, 15% Upper Midwestern, 0% Dixie and 0% Midwestern. Now I know this is not high linguistic analysis, but it is a surprisingly accurate interpretation based upon a short questionnaire of customary usage habits.Try it yourself and see what you think.
