crystal (English)
Where does "crystal" come from?
The English noun 'crystal' traces its lineage back to the Proto-Indo-European root '*krews-', meaning 'hard, hard outer surface, crust'[1]. This evolved into the Ancient Greek 'κρύσταλλος', meaning 'clear ice'[1]. The term was subsequently borrowed into Latin as 'crystallum', carrying meanings of both 'crystal' and 'ice'[1][3]. Through Old English 'cristalla', the word entered Middle English as 'crystal'[1]. The English vocabulary was later reinforced by Anglo-Norman 'cristall' and Middle French 'cristal'[1].
