This dictionary is a handy practical tool for Navajo language learners and teachers at various levels. It is meant to be a companion volume to 'The Navajo Language' book by Robert W. Young and William Morgan. The book deals largely with extended word meanings used in colloquial Navajo and encompasses 480 pages. Originally published in 1951 and printed by Phoenix Indian School, this publication is still the best alternative to the scholarly work Young and Morgan compiled later: in 1980 the two books were combined into a reference grammar and dictionary for the academic library.
