sign (n.)

13世纪初,"手的手势或动作",尤其是一个意在传达某事的手势或动作,来自古法语 signe "标志、标记",来自拉丁语 signum "识别标志、象征、指示、符号;证明;军事标准、标志;信号、预兆;天上的标志、星座"。

根据沃特金斯的说法,字面意思是"一个人遵循的标准",来自PIE *sekw-no- ,源于根 *sekw- (1)"遵循"。但德瓦安的说法是来自PIE *sekh-no- "切",来自PIE根 *sek- "切"他写道:"词源学上的附会 seco '切'意味着 *sek-no- '切出来的东西','刻出来的'>'标志'的语义转变。"但他也比较了希伯来语 sakkin ,阿拉姆语 sakkin "屠宰刀",并提到一个理论,"这两个词可能都是从未知的第三个来源借来的"。

它赶走了本土 token 。意思是"具有某种特殊重要性的标记或装置"是从13世纪末开始记录的;"奇迹"是从14世纪开始记录的。英语中的"黄道十二宫"是14世纪中叶开始的。"客栈、商店等门面的特征性装置,以区别于其他的"是15世纪中叶开始记录的。"某种状况的标志或信号"(13世纪末)是在后面。 sign of the times (1520s).在一些用途中,这个词可能是 ensign 的缩写。 Sign language 是1847年的记录;更早的 hand-language (1670年代)。

sign (v.)

14世纪,"做十字架的标志",来自古法语 signier "做标志(给某人);做标记",来自拉丁语 signare "在上面做标记,标出,指定;用印章做标记;区分,装饰;"形象地"指出,表示,表明",来自 signum "识别标记,标志"(见 sign (n.))。"标记、印记"的意义在14世纪中叶得到证明;"贴上自己的名字"的意义在15世纪晚期。"用手势交流"的意义在1700年就有记载。相关链接: Signed ; signing .
