When I moved to northern Indiana, I can't say I noticed a big difference--a few "kew-pons" for "coupons" and "warshing machines" for "washing machines."
But travel just a little south, and it's a different story--say, Hartford City.
I call it the Hoosier Drawl.
My husband's extended family has it, and when I read this article in Sunday's Journal-Gazette, I see that it's the southern shift affecting Blackford County residents.
Sometimes I wonder how American accents sound to people around the world--how do the difference in East Coast, Southern, or General American sound to a Brit? I know I can tell gross differences in British accents, say, Cockney from upper crust, but I'm not sure beyond that.
