Analysis. paṭi-nissa-gga-anu-passī: a compound of paṭinissagga (relinquishment, abandonment of craving) and anupassī (one who observes). paṭinissagga itself is paṭi (back, against) + nis (out of) + √gam (go) in the sense of 'letting go back' or 'releasing'; anupassī is anu (along after, following) + √pass (see), 'one who watches along with'.
Etymology. The root √pass (to see) cognates with English peer and German Paar in the sense of looking; √gam (to go) is an ancient root found in Latin venio (from *gwem-) and Greek βαίνω (bainō). The prefix paṭi- (back, against) derives from Proto-Indo-European *pret-i, related to Latin preti- and Greek proti (toward, against). The compound expresses the contemplative stance that follows the path of letting-go taught in the canon.
