Synopsis The present volume is the out come of a close study of the Rgvedapadapatha of Sakalya. The work is the first of its kind in the sense that it is for the first time that such detailed study of the entire Pada-text of Sakalya has been taken for analysis. Sakalya was a pre-Paninian, grammarian and no grammatical text of Sakalya other than the Pada-text of the Rgveda where Saklya has applied his knowledge of grammer is available with us today. Thus the present volume aims at reconstructing the knowledge of grammar of Sakalya. This work will help in tracing the history of grammatical thought in ancient India. This will also help in tracing the history of development of grammatical concepts of Panini.
