This comprehensive dictionary draws on ethnographic and linguistic work of the Aleut language and culture dating to 1745. An introductory section explains the dictionary's format, offers a brief historical survey, and contains notes on Aleut phonology and orthography, dialectal differences and developments, Eskimo-Aleut phonological correspondences, and Aleut treatment of Russian words. The main body of the dictionary is in two parts: basic words and derivatives, and suffixes. Following this are problematic words in older sources, appendixes, and an English index, with its own introduction. Appended materials include notes on demonstratives, directions of the wind, positional nouns, numerals, Aleut calendars, kinship terms, Ancient Aleut personal names, baidarka terminology, place names with maps, and loan words. An addendum contains information obtained while the dictionary was being typeset. (MSE)
