To attach feathers to an arrow to help it fly straight; also a surname.
From Old English 'flycce' (arrow) and 'flicce' (to fly), or possibly from Latin 'flectere' (to bend). The verb form developed because arrow-makers (fletchers) performed this task.
Interestingly, fletcher was such a common profession in medieval times that it became a surname—like Smith, Miller, or Cooper—and now 'fletch' echoes an entire forgotten profession of medieval craftspeople.
