strain (v.)

14世纪 ,"扎、绑、扣、束,"来自古法语 estreindre "绑紧、扣住、挤压"的现在分词干,来自拉丁语 stringere (2)"拉紧、捆紧、压紧、压在一起",来自PIE根 *streig- "抚摸、揉搓、按压"(也是立陶宛语 strėgti "凝固、冻结、变得僵硬"的来源。"希腊语 strangein "扭曲;"古高德语 strician "修补网;"古英语 streccian "伸展;"德语 stramm ,荷兰语 stram "僵硬")。)

从14世纪晚期开始作为"紧缩;使之绷紧",也有"用力;过度用力(身体部位)"的意思,"压过过滤器,把(液体)通过过滤器"的意思是从14世纪早期开始的(在 strainer 中有暗示);"强调到无法衡量,进行得太远,做出强行解释"的意思是从15世纪中期开始的相关: Strained ; straining

strain (n.1)

"拉紧造成的伤害",15世纪 ,出自 strain (v. )。"音乐的通道"(1570年代)的意思可能是从"收紧"声音的动词意义发展而来的,最初是指乐器的琴弦(14世纪末)。

strain (n.2)

"世系、血统、品种、祖先",13世纪 ,来自古英语 strionstreon "收益、获得、宝藏;生养、生育",来自原日耳曼语 *streu-nam- "堆积",来自PIE *streu- ,根 *stere- "传播"的扩展形式。

因此"种族,种群,线"(14世纪早期)。从17世纪开始应用于动物物种;通常涉及相当小的变化,但与 breed (n.)没有区别。正常的声音发展会产生 *streen ,但这个词在中世纪晚期英语中被改变了,显然是受 strain (n.1)的影响。
