'anathematized' originates from Late Latin, specifically the word 'anathematizare,' where 'anathema' meant 'a formal curse' and the suffix '-ize' meant 'to make or treat in a specified way.'

'anathematizare' transformed into the English verb 'anathematize,' and its past tense and past participle form became 'anathematized' in modern English.

Initially, it meant 'to formally curse or excommunicate,' but over time it evolved into its current meaning of 'to strongly condemn or denounce.'
