manifest: [14] That which is manifest is etymologically ‘grasped by the hand’ – that is, ‘palpable, obvious’. The word comes via Old French from Latin manifestus. This was a later form of manufestus, a compound formed from manus ‘hand’ and *festus ‘gripped’. Manifesto [17] is a borrowing from Italian; it originally meant ‘evidence, proof’, and only gradually developed to the present-day ‘political statement’. => manifesto, manual[manifest etymology, manifest origin, 英语词源]
