'anathematize' originates from Late Latin, specifically the word 'anathematizare,' where 'anathema' meant 'a curse' and the suffix '-izare' meant 'to make or do.'

'anathematize' changed from the Late Latin word 'anathematizare' to the French 'anathématiser,' and eventually became the modern English word 'anathematize.'

Initially, it meant 'to curse or excommunicate,' and over time it evolved into its current meaning of 'to formally condemn or denounce, especially by religious authority.'
