词汇 | tank |
词源 | tank. The motorized tank wasn’t invented until World War I. Winston Churchill, who advocated its use, gave it the name tank as a “cover name” to help conceal the new weapon from enemy intelligence agents. Before this, tank had absolutely no connection with war. Possibly deriving from the Indian tankh, it had for centuries meant an irrigation pond and then a cistern holding water. The British brought the word back from India, using it exclusively as the term for any large metal container holding any liquid (such as gas and oil tanks) until Churchill appropriated the word. |
