This dictionary covers the Central Yup'ik Eskimo language spoken in southwestern Alaska. An introductory section provides notes on Yup'ik phonology and orthography, outlines the volume's format, discusses several special issues in translation and phonology, and describes a number of dialects. The main section of the dictionary lists base words, with subsequent smaller sections devoted to postbases, endings, enclitics, and unverified words from older sources. Appendixes contain notes on inflection of personal pronouns, inflection of the independent relative pronoun, demonstratives, positional bases, lists of roots by type, numerals, calendar, kinship terms, and loan words, and a map. An English-to-Yup'ik index is also included.
