(Chickasaw) from:
Humes, James and Humes, Vinnie May James. A Concise Chickasaw Dictionary. Chickasaw Press, 2015.
The book shows the correct pronunciation of the Chickasaw words used in this application. Some of the Chickasaw tree names listed may be names of the fruit or edible portion. The Chickasaws were the native peoples of North Mississippi (and surrounding areas) and are the Brother Tribe to the Choctaw people.
(iti, itti’ = tree): The first word is the original Humes orthography, the second word is updated from the Munro-Willmond orthography (Humes xv) as incorporated and edited by Lokosh (Joshua D. Hinson).
