carburettor: [19] Carburettor is a derivative of carburet, an obsolete term for what is now known as carbide ‘a carbon compound’. It was originally used for a device for adding carbon to a gas for enhancing its power of illumination; the current application to a device for producing air/fuel vapour in an engine dates from the 1890s. Carburet itself was a later form of carbure, borrowed in the 1790s from French; its ultimate origin was in Latin carbō, source of English carbon. => carbon
