horizon: [14] Etymologically, the horizon is simply a ‘line forming a boundary’. The word comes via Old French orizon and late Latin horīzōn from Greek horízōn, a derivative of the verb horīzein ‘divide, separate’ (source also of English aphorism [16], originally a ‘definition’). This in turn came from the noun hóros ‘boundary, limit’. Horizontal [16], which came either from French or directly from late Latin, originally meant simply ‘of the horizon’; it was not until the 17th century that it began to be used in its modern sense ‘flat, level’.
