empire (n.)

14世纪中叶, “受皇帝统治的领土;” 一般为“境界, 统治”; 14世纪末为“皇帝的权威, 统治的最高权力; 帝国权力”, 中古英语一般为罗马帝国.

来自古法语 empire “统治, 权威, 王国, 帝国统治” (11世纪), 来自拉丁文 imperium “一个规则, 一个命令; 权威, 控制, 权力; 最高权力, 唯一统治; 军事权威; 一个统治, 境界”, 来自 imperare “命令”, 来自 in- “在” (来自PIE根 *en “在” )+ parare “命令, 准备” (来自PIE根 *pere- (1) “生产, 采购” )的同化形式.

在词源上不限于“皇帝统治的领土”, 而是这样使用. The Empire, 意为“大英帝国”, 最早记载于1772年(1931年正式下放为“英联邦” ); 在此之前是指神圣罗马帝国(1670年代).
