Collude Has Latin Roots
The Latin prefix col-, meaning "together," and the verb ludere, "to play," come together to form collude. The related noun collusion has the specific meaning "secret agreement or cooperation." Despite their playful history, collude and collusion have always suggested deceit or trickery rather than good-natured fun.
