vertical的词源
英文词源
- vertical
- vertical: [16] Latin vertex originally meant ‘whirl’ (it was derived from vertere ‘turn’, source also of English verse, version, etc, and was itself borrowed into English in the 16th century). It came to be applied metaphorically to the ‘spiral of hair on top of the head’, and was then extended further to ‘highest point’. From it was derived late Latin verticālis, which passed into English via French vertical.
It originally denoted ‘of the highest point in the sky, the zenith’, and since this is directly overhead, by the 18th century vertical had come to be used for ‘perpendicular’. Also from vertere came Latin vertīgō ‘whirling’, borrowed into English as vertigo ‘dizziness’ [16].
=> verse - vertical (adj.)
- 1550s, "of or at the vertex, directly overhead," from Middle French vertical (1540s), from Late Latin verticalis "overhead," from Latin vertex (genitive verticis) "highest point" (see vertex). Meaning "straight up and down" is first recorded 1704. As a noun meaning "the vertical position or line" from 1834. Related: Vertically.

人们在测量建筑是否垂直时，常使用铅垂线，先找到一个顶点，再垂下重物，绳子受重力作用而成垂线。所以该词先表“顶点的”，后引申出“垂直的”。“顶点”之义何来？词根vert表“转”，它本指盘旋而上的东西，到达顶部就形成了一个顶点。
