Etymology

The word "crystalline" derives from the Latin "crystallinus," which itself comes from the Greek "krustallos" (ice, crystal). The suffix "-ine" (from Latin "-inus") denotes "pertaining to" or "resembling." Historically, "crystal" referred to quartz or ice due to its clarity, and the term evolved to describe any transparent, geometrically structured solid. The modern scientific sense (referring to atomic/molecular order) emerged in the 17th century.
