The work is well planned and systematically executed. The methodology adopted is convincing and the principles followed are sound. It follows the same method as in Dr. S.D. Laddu's work of the same name but dealing with a different set of primary suffixes, and is, in a way, its continuation. The suffixes in question are classified on the basis of the tenses they are laid down to denote, and, under each, the illustrations are examined with regard to their form and significance. The author is well aware of the difficulties in the sources, namely the Sutras, Varttikas and Bhasya, present in understanding them aright as well as the facilities they present in the matter. The investigation, though confined to a small section of the vast Planiniyan system is thorough and the finding generally acceptable.
