The dictionary is based on the Ngaanyatjarra dialect of the Western Desert Language. It was designed originally to bridge the gap between my description of the grammar of the Western Desert Language (Oceanic Linguistic Monographs, No 4 Revised 1964) and the anticipated comprehensive dictionary which has been submitted by Misses A Glass and D Hackett for publication in Alice Springs this year. Some spelling alterations have been made in this edition to be consistent with those in the Glass and Hackett work.
