Carolyn Quintero, a linguist raised in Osage County, worked with the last few fluent speakers of the language to preserve the sounds and textures of their complex speech. Compiled after painstaking work with these tribal elders, her Osage Dictionary is the definitive lexicon for that tongue, enhanced with thousands of phrases and sentences that illustrate fine points of usage.Drawing on a collaboration with the late Robert Bristow, an amateur linguist who had compiled copious notes toward an Osage dictionary, Quintero interviewed more than a dozen Osage speakers to explore crucial aspects of their language.
