Origin

  1. Ancient Greekβασιλίσκος
  2. Latinbasiliscus
  3. Old Frenchbasilique
  4. Middle Englishbasilicke
  5. Englishbasilisk

From Middle English basilicke, borrowed from Old French basilique, from Latin basiliscus, from Ancient Greek βασιλίσκος (basilískos, literally “minor king or chieftain”), from βασιλεύς (basileús, “king”), possibly based on descriptions or rare encounters with different types of cobra which have crown-like patterns on their head; the 'deadly gaze' may have been from the spitting cobra's ability to spit venom into the eyes of predators or prey from a distance. The infohazard sense is a figurative reference to the deadly gaze of the mythical creature. Displaced native Old English fāgwyrm.
