'adjuratory' originates from Latin, specifically the word 'adjurare,' where 'ad-' meant 'to' and 'jurare' meant 'swear.'

'adjurare' transformed into the Medieval Latin word 'adjuratorius,' and eventually became the modern English word 'adjuratory.'

Initially, it meant 'to swear an oath,' but over time it evolved into its current meaning of 'relating to an earnest appeal or request.'
