neuter nominative/accusative singular + ca (and); paṭipadañca is a sandhi contraction
Analysis. paṭipada + ca (and); the final -a of paṭipada assimilates with ca to -añca in sandhi.
Etymology. paṭi (back, against, in return) + pada (foot, step, place). The prefix paṭi- suggests a turning-back or counter-movement: the path as a way one treads in response to a challenge, a practice undertaken as a deliberate response or counter to ignorance. Cognate with Sanskrit paṭhapad, though the canonical sense emphasizes methodical practice and the *way* itself rather than merely a track.
