Origin of 'gearwheel'

Main points about word origin

  • The word 'gear' comes from the Old English 'gier' meaning 'to turn' or 'to move'.
  • The term 'wheel' has roots in the Proto-Indo-European word 'weḱ-', which means 'to turn or roll'.
  • When combined, 'gear' and 'wheel' reflect the purpose of aiding movement in machinery.

The term 'gearwheel' originates from the combination of 'gear', which refers to a toothed wheel that engages with another toothed component, and 'wheel', a circular object that rotates. Gearwheels have been used in various mechanical systems since ancient times, with advancements in design and technology leading to the development of modern gear systems for industrial and transportation applications.
