      英文詞源


      shear
      shear: [OE] Shear is the principal English descendant of the Indo-European base *sker- ‘cut’, which has also produced English score, share, shirt, short, and skirt, and probably sharp and shore as well. A variant of the base without the s is responsible for curt and curtail. The immediate source of shear itself is prehistoric Germanic *skeran, which also evolved into German and Dutch scheren, Swedish sk?ra, and Danish skj?re.

      The verb sheer ‘swerve’ [17] probably originated as a variant of shear, but the adjective sheer [16] is an entirely different word. It probably represents a survival of Old English scīr ‘bright, shining’, which came ultimately from the Germanic base *ski-, source also of English shimmer and shine.

      => curt, curtail, score, share, sheer, shirt, short, skirt
      shear (v.)
