Analysis. kāya (body) + anupassī (one who observes); anupassī itself is anu- (following along) + passī (seeing), from √pas (see). The compound names a meditator who contemplates the body systematically, a central practice in the Satipaṭṭhāna Sutta.
Etymology. kāya is from √kāy (shape, form), cognate with Greek khea (pour, flow into shape). anupassī: anu- (following, along) + √pas (see), where √pas is cognate with Latin passus (step, passage—seeing as a stepping forward through phenomena). The prefix anu- originally meant trailing behind or following a track; here it captures the sustained, sequential attention that characterizes mindfulness practice.
