Chicago is an Indian word meaning stinky onion
There's another explanation for the meaning of Chicago that I am partial to. The story goes that some Indians from outside the area asked some local Indians for a good place to hunt. They were pointed toward where Chicago is. When they got there, the only "game" they found were skunks. So Chicago could also mean, "place of the skunks." Considering the way things have turned out, that has become a kind of parable.
