A Chickasaw word meaning "be quiet," but with a much more interesting etymology. When Hernando de Soto came to
America, he asked the Apalachee who lived in a certain village, and they said "Chikashsha," which means "abandoned town" in their language. Apparently the Chickasaw thought this was funny, as they weren't gone, so they decided to go by that
name. "Chokkilissa," however, is a translation of "Chikashsha" into the Chickasaw language. Chokkilissa can be broken down a few ways, but they generally
mean the same thing. CHOKKA'+ILLA+ISSA, "only quit the
house" or CHOKKA'+ILISSA, "we quit the
house." "Quitting the
house" can be seen as "abandoning the village," as the two seem to be close in meaning. As an abandoned village is quiet, it can be seen why this word would be defined in this way. This is only a theory, so it could be false.
