Origin & History of “policy”

English has two distinct and completely unrelated words policy. The one meaning ‘plan of action’ (14th c.) comes via Old French policie from Latin polītīa ‘civil administration’, source also of English police and the now archaic polity (16th c.). this in turn came from Greek polīteíā, a derivative of pólis ‘city’ (source of English politics). But the insurance policy (16th c.) comes via French police ‘document’ and Provençal polissa from medieval Latin apodissa, an alteration of Latin apodīxis ‘proof, demonstration’, which in turn was acquired from Greek apódeixis, a compound noun derived ultimately from the verb deiknúnai ‘show’.
