masc dat sg of atthaṅgama (noun)
Analysis. atthaṅgama is a bahuvrīhi compound: attha (direction home, goal) + ṅgama (going). Lit. 'going to the goal/home'; used of the sun's descent and the fading of phenomena.
Etymology. attha is from √i 'go' (related to Latin ire, English iterant); ṅgama is from √gam 'go' (related to come, English come). The prefix a- here marks direction 'toward'; the compound frames 'going' as motion toward a destination or rest-point, hence 'setting' and 'subsiding'.
