The affix kyap comes after a roots 1. vraja 'to go' 2. yaj 'to worship' acutely accented (udātta) in forming a word in the feminine denoting action.,
This supersedes क्तिन्. Thus व्रज्या 'wandering about'; इज्या 6.1.15 'worshipping'. The प् of क्यप् is indicatory, and though it serves no purpose in this sutra, it is, however, necessary in the next, for it is by force of क्यप् having प् that we add a त by (VI 1. 71), in the words formed in the next aphorism.,
