Etymology. From √sah (to bear, endure, overcome); satthar is the agent noun meaning 'one who bears or masters'. Cognate with Sanskrit śāsṛ, Greek ἄρχω (archō, 'to rule, lead'), and English 'sustain' (via Latin sustinēre). The notion of 'mastery' flows from the concrete sense of bearing weight or overcoming resistance.
