odour: [13] The Latin noun for ‘smell’ was odor. It was descended from the Indo-European base *od-, source also of the Greek verb ózein ‘smell’ (from which English gets ozone [19]), the Latin verb olēre ‘smell’ (ancestor of English redolent), and the Latin verb olfacere ‘smell’ (source of English olfactory). It passed into English via Anglo-Norman odour. (It has, incidentally, no etymological connection with odious [14], which comes from Latin odium ‘hatred’.)
