Before there was a Hot in Herre, there was Highway Farty and carn on the cob. No, I’m not having a stroke, I’m referring to the dialect that I heard as a child growing up in St. Louis. Citylab recently had a post explaining the St. Louis accent.
The most stereotypical St. Louis pronunciation is “farty” for “forty.” St. Louisans swap an “ar” for an “or” sound, so they eat “carn on the cob” and wish each other “good marning.” This is unique to St. Louis, but the city has other features in common with the Midlands. Older St. Louisans say “worsh” for “wash,” “wants off” for “wants to get off,” and “I waited on him” instead of “I waited for him.”
The whole article is pretty fascinating. Go and give it a read.
