yāska यास्क

Definition: a reputed ancient Niruktakara or etymologist, of the 6th century B.C. or even a few centuries before that, whose work, the Nirukta, is looked upon as the oldest authoritative treatise regarding derivation of Vedic words. Yaska was preceded by a number of etymologists whom he has mentioned in his work and whose works he has utilised. Yaska's Nirukta threw into the back-ground the older treatises on etymology, all of which disappeared gradually in the course of time.
