Morphology

Mississippian = Mississippi (semi-transparent) = Mississippi + ian

Formed from the place name with a standard suffix, but the sense 'a named geological period' is specialized and not directly inferable by general learners.

Etymology

Mississippian as a geological name comes from Mississippi, from Native American Misi-ziibi meaning 'big river'. Scientists named the time after the area because rocks of that age were first studied near the river, so the name links the period to that region.
