Origin of crystal

  • Middle English cristal from Old French from Latin crystallum from Greek krustallos ice, crystal kreus- in Indo-European roots
    From American Heritage Dictionary of the English Language, 5th Edition
  • Old English cristal (“clear ice/mineral”), from Latin crystallum (“crystal, ice”), later reinforced from Anglo-Norman cristall, Middle French cristal, from Latin crystallum, from Ancient Greek κρύσταλλος (krustallos, “clear ice”), from κρύος (kruos, “frost”), from the Proto-Indo-European *krus-, *kru- (“hard, hard outer surface, crust”).
