'granulate' originates from Latin, specifically the word 'granulatus', where 'granulum' meant 'small grain'.

'granulate' changed from Latin 'granulatus' (past participle of 'granulare') and entered English via New Latin/technical usage, eventually becoming the modern English verb 'granulate'.

Initially, it meant 'to make into small grains or granules', and over time it has retained that core meaning in modern usage.
