Did you know?
Colluding—working secretly with others to do something deceitful or illegal—is not a game, but you'd never know it if you took your cues on the meaning of
collude solely from its etymology.
Collude comes from the Latin verb
colludere, which in turn combines the prefix
com-, meaning "together," and the verb
ludere, "to play."
Ludere, in turn, comes from
ludus, meaning "game, play, or sport." (
Ludus is also the source of the adjective
ludicrous and the noun
interlude).
Collude has a related noun—
collusion—which carries the specific meaning "secret agreement or cooperation." Despite their playful history,
collude and
collusion have always suggested illicit trickery rather than good-natured fun.
