'conjure' originates from Latin, specifically the word 'conjurare,' where 'con-' meant 'together' and 'jurare' meant 'to swear.'

'conjurare' transformed into the Old French word 'conjurer,' and eventually became the modern English word 'conjure' through Middle English.

Initially, it meant 'to swear together,' but over time it evolved into its current meaning of 'to call upon or command a spirit.'
