stem词源中文解释

[树的主干] Middle English stemme,源自 Old English stemn, stefn "树或灌木的主干",这部分从地面升起并支撑枝干; 也指"船的两端柱"; 源自 Proto-Germanic *stamniz (源自 Old Saxon stamm, Old Norse stafn "船的主干"; Danish stamme, Swedish stam "树的主干"; Old High German stam, German Stamm)。这被认为是 PIE root *sta- "站立,使之或保持坚固"的一个带后缀的形式。

特别指船头的柱子,因此到了1550年代,这个词开始泛指"船的前部"。这个含义保留在短语stem to stern中,这是一个原本的航海术语,意为"沿着全长"(指船),并在1620年代得到证实。

到了1590年代,它被用来指"支撑植物花朵的茎"; "酒杯的支撑"的含义出现在1835年。扩展到其他类似植物茎的东西; 在铸字中,"字母的粗笔画"(1670年代); stems作为"腿"的俚语出现在1860年。

"家族的血统,祖先"的含义在1530年代得到证实; 这个含义也存在于 Middle High German stam, Dutch stam; Old High German stam 只有字面上的含义,但在复合词 liut-stam 中意为"种族"; 也可以参考 Old English leodstefn "种族"。

在现代语言学中,"词的部分在词形变化中保持不变"的含义出现在1830年。在生物学中,stem cell在1885年得到证实。
