Secret or illegal cooperation or conspiracy, especially in order to cheat or deceive others.

Collusion implies a secret agreement between two or more parties to act together, often to limit competition, deceive a third party, or achieve an illegal objective. It's about a hidden partnership for illicit gain.

The story behind the word. The word 'collusion' comes from the Latin 'colludere,' meaning 'to play together,' 'to conspire.' This root is formed from 'com-' (together) and 'ludere' (to play). While 'play' might sound innocent, in this context, it refers to playing a game of deception together, often against a third party. It entered English in the 15th century, specifically referring to secret agreements for fraudulent or illegal purposes, highlighting the deceptive 'game' being played.
