Anybody who's driven here in Detroit even for a few months has come across many of our major streets with names such as Gratiot, Dequindre, Charlevoix, or Jos Campau. This is no surprise given our French heritage. After all it was a man by the name of Cadillac that founded the city. He named the original settlement after Riviere D'etroit which means "River of The Strait" in French, (referring to the Detroit river which is the strait from Lake St. Claire to the Detroit River). What have we done to honor our founder's culture? Massacre the many French names. If I remember my 3 years of high school French correctly, Detroit should be pronounced "day-twoi", Gratiot shouldn't be "gra-shit" but "grah-she-oh", Dequindre should be pronounced "de-can-druh", and Charlevoix should be spoken as "Char-le-vwoi". I know that my bringing this up isn't going to change our habits, but we should remember the origins of our great city, and just considering the original way to say the street names will keep it in our minds.
