Vyutpattivada of Gadadhara Bhattacharya, a work on Shabdabodha, kept engaged several generations of scholars in India on exploring and explicating the theories and principles of Linguistic understanding or sentential cognition. The Naiyayikas and the Vaiyakaranas, though differ on many issues regarding the scholastic representation of linguistic understanding, accept the authenticity of Vyutpattivada with great esteem and appreciation, Vyutpattivada presents all the principles of linguistic understanding being debated upon in an unbroken tradition in India for several millenniums. It is therefore, Vyutpattivada is said to be most valuable contribution to the language philosophy in general and onShabdabodha in particular in the Indian intellectual tradition. Gadadhara Bhattacharya has very systematically dealt with the theory of linguistic understanding (Shbdabodha) in his Vyutpattivada, a discourse on the logical principles on linguistic understanding [ vyutpatti means nimaya-visesah, i.e. the logico-linguistic principles, and vada means a discourse ]. This book contains the main text of Vyutpattivada along with seven commentaries in Sanskrit with a broad Introduction in English.
