The Traditional Nighantu

According to Yaska (Nirukta 1.20), the Nighantu was a collection of rare or difficult words gathered by earlier sages for easier understanding of Vedic texts that perhaps they may not have fully understood themselves. The collection comprises five ''adhyāya''s or chapters, in three 's or books: * : three ''adhyāya''s of similes, synonyms, metonyms and other glosses. The first ''adhyāya'' deals mainly with physical things and objects of nature. The second ''adhyāya'' deals mainly with man, his physical being, and qualities associated with his being, such as property and emotional states. The third ''adhyāya'' deals mainly with abstract qualities and concepts. * : one ''adhyāya'' of homonyms (''aikapadikam'') and particularly difficult or ambiguous words. * : one ''adhyāya'' of epithets of divine beings. Yaska's Nirukta covers the Naighantuka somewhat synoptically, often merely echoing a given gloss, but deals with the 278 words of the Naigama and the 151 names of the Daivata in detail. A full word-by-word commentary on the Naighantuka was written by Devarajayajvan, some time before the 14th CE.Sarup, Part I, p.50 A critical edition of the Nighantu and the Nirukta was published in the 1920s by Lakshman Sarup. In it, two major recensions were identified, one longer than the other, indicating additions at untraceable yet relatively early dates. It is now customary to render both recensions together, with the additions of the longer recension in parentheses.
