'anathematisation' originates from Medieval Latin, specifically the word 'anathematizare,' where 'anathema' meant 'a formal curse' and '-izare' meant 'to make or to do.'

'anathematizare' transformed into the English word 'anathematise,' and the noun form 'anathematisation' was formed by adding the suffix '-ation.'

Initially, it meant 'the act of cursing or excommunicating,' and this meaning has largely remained the same in modern usage, referring to formal denunciation or condemnation.
