Emeneau contributed study of the lesser known, non-literary languages of the Dravidian family. His work on the Toda language remains essential reading for students of Dravidian. His phonetic descriptions of the language, based on impressionistic data collection without the aid of recording devices, was corroborated some 60 years later by the eminent phoneticians
Peter Ladefoged and Peri Bhaskararao using modern phonetic methods. His linguistic descriptions of Dravidian languages were often accompanied by sociolinguistic, folkloric, and ethnographic description. Emeneau is also credited with the study of
areal phenomena in linguistics, with his seminal article,
India as a Linguistic Area. Emeneau's contribution to Dravidian linguistics includes detailed descriptions of
Toda,
Badaga,
Kolami, and
Kota. Perhaps Emeneau's greatest achievement in Dravidian studies is the
Dravidian Etymological Dictionary (in two volumes), written with Thomas Burrow and first published in 1961. Despite the characteristic reserve that eschewed historical reconstruction, this work, revised in a 1984 second edition, remains the indispensable guide, tool, and authority for every Dravidianist. ==Professional achievements==
