What is the meaning of Chicago?

The name Chicago is derived from the local Indian Word chicagoua for the native garlic plant (not onion) Allium tricoccum. This garlic (in French: ail sauvage) grew in abundance on the south end of Lake Michigan on the wooded banks of the extensive river system which bore the same name, chicagoua. Father Gravier, a thorough student of the local Miami language, introduced the spelling chicagoua, or chicagou8, in the 1690s, attempting to express the inflection which the Indians gave to the last syllable of the Word.
