Itâ??s axiomatic that even on the East Coast long sandwiches go by a host of names: hero (especially New York City), grinder (chiefly in New England), hoagie (mainly in Pennsylvania and New Jersey) and submarine (everywhere). Only if youâ??re an aficionado of the Dictionary of American Regional English are you likely to know that when kids still play hopscotch, they may call it “potsy” in Manhattanâ??but itâ??s “sky blue” in Chicago.
