The Alabama language, a member of the Muskogean language family, is spoken today by the several hundred inhabitants of the Alabama-Coushatta Indian Reservation in Polk County, Texas. This dictionary of Alabama was begun over fifty years ago by tribe member Cora Sylestine. She was aided after 1980 by linguists Heather K. Hardy and Timothy Montler, who completed work on the dictionary after her death.

This state-of-the-art analytical dictionary contains over 8,000 entries of roots, stems, and compounds in the Alabama-English section. Each entry contains precise definitions, full grammatical analyses, agreement and other part-of-speech classifications, variant pronunciations, example sentences, and extensive cross-references to stem entries. The Alabama-English section is followed by a thorough English-Alabama finder list that functions as a full index to the definitions in the Alabama-English section.
