From Greek krystallos (clear ice), from kryos (frost). The ancient Greeks believed rock crystal was ice frozen so deeply it could never melt. In modern English it spans transparent minerals (crystal, crystalline), the process of solidification (crystallize, crystallization), and metaphorical clarity.
