Origin of cockatrice

First recorded in 1350–1400; Middle English cocatrice, from Middle French cocatris, from Medieval Latin caucātrīces (plural), Latin calcātrīx (unattested), feminine of calcātor (unattested) ”tracker,” equivalent to calcā(re) “to tread,” verbal derivative of calx “heel” + -tor agent suffix; the Latin was a direct translation of Greek word ichneúmōn, having the same meaning. See -trix, -tor, ichneumon
