Toponymy or what's in a name?

to·pon·y·my /təˈpänəmē/ noun = the study of place names.  For example, some places are derived from topigraphical features:

1. Montana means "mountains" in Spanish.
2. Mississippi means "big river" in Chippewa.
3. Moccasin Bend describes the Cherokee name for where the Tennessee River is foot-shaped, and they wore moccasins on their feet.

Below are moccasins like I'm wearing right now.
