Cherokee, the name by which they are commonly known, has no meaning in their own language, and seems to be of foreign origin. As used among themselves the form is Tsa'lagi' or Tsa'ragi'. It first appears as Chalaque in the Portuguese narrative of De Soto's expedition, published originally in 1557, while we find Cheraqui in a French document of 1699, and Cherokee as an English form as early, at least, as 1708. The name has thus an authentic history of 360 years. There is evidence that it is derived from the Choctaw word choluk or chiluk, signifying a pit or cave, and comes to us through the so-called Mobilian trade language, a corrupted Choctaw jargon formerly used as the medium of communication among all the tribes of the Gulf states, as far north as the mouth of the Ohio (2). Within this area many of the tribes were commonly known under Choctaw names, even though of widely differing linguistic stocks, and if such a name existed for the Cherokee it must undoubtedly have been communicated to the first Spanish explorers by De Soto's interpreters. This theory is borne out by their Iroquois (Mohawk) name, Oyata'ge`ronoñ', as given by Hewitt, signifying "inhabitants of the cave country," the Allegheny region being peculiarly a cave country, in which "rock shelters," containing numerous traces of Indian occupancy, are of frequent occurrence. Their Catawba name also, Mañterañ, as given by Gatschet, signifying "coming out of the ground," seems to contain the same reference. Adair's attempt to connect the name Cherokee with their word for fire, atsila, is an error founded upon imperfect knowledge of the language. Among other synonyms for the tribe are Rickahockan, or Rechahecrian, the ancient Powhatan name, and Tallige', or Tallige'wi, the ancient name used in the Walam Olum chronicle of the Lenape'. Concerning both the application and the etymology of this last name there has been much dispute, but there seems no reasonable doubt as to the identity of the people. Linguistically the Cherokee belong to the Iroquoian stock, the relationship having been suspected by Barton over a century ago, and by Gallatin and Hale at a later period, and definitely established by Hewitt in 1887. [2] While there can now be no question of the connection, the marked lexical and grammatical differences indicate that the separation must have occurred at a very early period. As is usually the case with a large tribe occupying an extensive territory, the language is spoken in several dialects, the principal of which may, for want of other names, be conveniently designated as the Eastern, Middle, and Western. Adair's classification into "Ayrate" (e'ladi), or low, and "Ottare" (â'tali), or mountainous, must be rejected as imperfect.
