Forms
collūsiō f (genitive collūsiōnis); third declension[1] It was also spelled conlūsiō.[2][3]
Etymology
It is from Latin collūdō + -tiō, a noun of action from the verb meaning “to play together; to act in collusion”.[2][1][4] The verb is formed from con- and lūdō (“to play”),[5] which de Vaan traces to Proto-Italic *loid-e/o- and Proto-Indo-European *loid- (“to let go frequently, play”).[6]
Earliest recorded meaning
Its first use is in Cicero's speeches against Verres, of the secret understanding between Verres' companions and the tax collectors.[2][7]
Semantic evolution
The TLL notes that Cicero and Apuleius use it once each, the elder Seneca twice, and the jurists very often.[4] It always meant a secret, deceptive understanding: between a girl's father and her abductor in Seneca's declamations, between husband and wife in Apuleius,[2][3] and between parties to a lawsuit in the Digest.[2][8]
Medieval writers kept the legal sense and also used it literally, of playing or joking together.[9] English borrowed it as collusion in the late 14th century, through Old French and directly from Latin.[5]
