Etymology

The word "reversible" traces back to Latin roots:

  • "re-" (back) + "vertere" (to turn), forming "reversus" (turned back).
  • The suffix "-ible" (from Latin "-ibilis") denotes capability.
    The term evolved in Middle French as "reversible" before entering English, retaining the core idea of "able to be turned back." Its modern meanings—from physical reversibility to adaptable clothing—logically extend this original concept.
