absolutive (perfective participle) of paṭinivattati
Analysis. paṭi- (back, against) + ni- (down, into) + vattati (turns, rolls). The prefix paṭi- reverses the motion, while ni- adds the sense of descent or reversion; together they depict turning back down the path one came.
Etymology. vattati is the present stem of √vṛt (Sanskrit vartate, Latin vertō 'turn', English 'vert' in revert/invert). The two prefixes are layered: paṭi- gives the return-motion sense (as in paṭiccasamuppāda), and ni- reinforces downward/inward reversal.
