- locomotive
[locomotive 词源字典] - locomotive: [17] Locomotive denotes etymologically ‘moving by change of place’. It is an anglicization of modern Latin locōmōtīvus, a compound formed from locus ‘place’ and mōtīvus ‘causing to move’ (source of English motive). Originally it was used strictly as an adjective, and it was not until the early 19th century that the present-day noun use (which began life as an abbreviation of locomotive engine) emerged.
