masc dat sg of samaṇa (noun); masc gen sg of samaṇa (noun)
Etymology. From sam- (together) + √aṇ or √aṇṇa (to move, exert effort). The concrete sense is 'one who gathers oneself together' or 'one who exerts effort': sam- (together, with complete application) + agent noun. The root connects to Sanskrit root aṇ and aṇṇa, relating to motion and strain. The word shifted from 'one who makes effort' to 'ascetic who disciplines body and mind through practised exertion', and became the standard Pali term for monk.
