'recrystallized' originates from English formation using the prefix 're-' (from Latin 're-' meaning 'again') + the verb 'crystallize' (from Late Latin/Greek roots), where 'crystall-' came from Greek meaning 'ice' or 'crystal'.

'crystal' comes from Greek 'krystallos' → Late Latin 'crystallus' → Old French 'cristal' → Middle English 'crystal'; the verb 'crystallize' was formed in Modern English from these roots, and 'recrystallize' (with the prefix 're-') developed to mean 'to crystallize again', later producing the adjective/past form 'recrystallized'.

Initially related to 'crystal' meaning 'ice' or 'clear ice' and 'to form into crystals'; over time the verb came to mean 'to form crystals' and with the prefix 're-' specifically 'to form crystals again' — the modern usage often refers to processes in chemistry, geology, and metallurgy.
