Harvard has done a study on various dialectic variations across the United States. Fascinating stuff. Thanks to kuro5hin for the link.
They missed a few terms from here in Amish land, like “red up your desk” or “want to go with?” or”want some coffee awhile?” My personal chalkboard screeching grammatical slaughter here is “Your car needs washed.” Washing, people, or to be washed. (Aaaggh!)
