/ˈtɛðər/
tether 作名词,指拴住动物的绳索或链条,限制其活动范围;作动词,指用绳索将动物或物体拴在某处。引申义为"限度、极限",常见于短语 at the end of one's tether(忍无可忍,精疲力竭)。
The farmer tethered the goat to a wooden post in the yard.
农夫把山羊拴在院子里的木桩上。
After months of dealing with endless problems at work, she felt she was at the end of her tether and seriously considered resigning.
在工作中应付了几个月没完没了的问题后,她觉得自己已经忍无可忍,认真考虑辞职了。
tether 源自古诺尔斯语 tjóðr,意为"拴牲畜的绳索",与中古英语 teder 同源。该词在日耳曼语族中广泛存在,原始含义就是用来限制动物活动范围的绳索。后来引申出"限制、约束"的抽象含义,产生了 at the end of one's tether 这一常用习语,比喻一个人的耐心或能力已经到了极限。
