Arabic The word kristal is derived from the Arabic billūr (بلّور), meaning "transparent and precious stone". According to the morphological rules of Arabic, it originates from the verbal noun taballur (تبلّر), formed by applying the tafaˁˁul (fifth form) pattern to billūr. This verbal noun pattern imparts the meaning of "becoming something", "completing a process", or "acquiring a quality". Thus, taballur etymologically represents the process of "becoming crystalline", that is, the transformation of a solid substance into a transparent and geometrically structured form.
