Origin

Middle English: from Anglo-Norman French poeir, from an alteration of Latin posse 'be able'.

Like posse, power can be traced back to Latin posse ‘to be able’. ‘We know that power does corrupt, and that we cannot trust kings to have loving hearts’, wrote Anthony Trollope in The Prime Minister (1876). But power corrupts got into the language through the slightly later quotation from Lord Acton: ‘Power tends to corrupt, and absolute power corrupts absolutely. Great men are almost always bad men, even when they exercise influence and not authority’ (letter to Bishop Mandell Creighton, 1887). Whoever the authorities or people in control are in a particular situation can be referred to as the powers that be, a phrase that comes from the Bible: ‘For there is no power but of God: the powers that be are ordained of God’ (Epistle to the Romans).
