Yāska's Nirukta (ca. fifth-third century bce), the seminal text of the Sanskritic discipline of nirvacana or ‘etymology’, is one of the most important yet least studied late Vedic texts. Particularly little attention has been paid to Nirukta Chapter 7. This chapter outlines Yāska's views on Vedic deities and articulates the hermeneutic principles whereby they are classified and defined. It plays a crucial, yet underappreciated, role in the history of ancient India's theological and hermeneutical speculations. The absence of an accessible English translation, which tackles the text's many conceptual and linguistic complexities, is the main reason why Nirukta Chapter 7 has not received the attention it deserves. We offer the first complete annotated English translation in a century. A comprehensive introduction clarifies the structure and rationale of Chapter 7 and elucidates the salient features of Yāska's theology.
