'collusion' originates from Latin, specifically the word 'collusio,' where 'col-' meant 'together' and 'ludere' meant 'to play.'

'collusio' transformed into the Old French word 'collusion,' and eventually became the modern English word 'collusion' through Middle English.

Initially, it meant 'playing together,' but over time it evolved into its current meaning of 'secret cooperation for deceitful purposes.'
