manner: [12] Etymologically, a manner is a method of ‘handling’ something. It comes via Anglo-Norman manere from Vulgar Latin *manuāria ‘way of handling’. This was a noun use of the Latin adjective manuārius ‘of the hand’, a derivative of manus ‘hand’. The adoption of manner as a conventional translation of Latin modus ‘method’ helped to establish the far broader range of meanings it has today.
