Etymology

Origin of Appalachian

First recorded in 1670–80; from Spanish Apalchen, Apalachen, perhaps from Apalachee (an extinct Muskogean language) abalahci “other side of the river” or from Hitchiti (an extinct Muskogean language) apalwahči “dwelling on one side”; the Spanish transcription of the name of a Muskogean village near Tallahassee in the Florida panhandle, recorded on the expedition led by Pánfilo de Narváez (1478?–1528), later altered by the Spanish to Apalachee and applied to the Indian tribe, the surrounding area and the hinterland north to the southern end of the Appalachian Mountains
