Forms
collūsor m (genitive collūsōris); third declension[1] It is also spelled conlūsor.[2][3]
Etymology
It is from Latin collūdō (“to play together”) + -tor.[2][1][4] That verb is formed with con- from lūdō (“to play”),[2] which goes back to Proto-Italic *loid-e/o- (“to play”) and Proto-Indo-European *loid- (“to let go frequently, play”).[5]
Earliest recorded meaning
It is first found in Lucilius,[6] in the sense of a fellow gambler: Coelius, collūsor Gallōnī, “Coelius, the gaming partner of Gallonius”.[2]
Semantic evolution
It meant a companion in play, of children and of games of skill: Seneca uses it of the partner to whom a good player throws the ball differently according to his height,[2][7] Pliny the Younger of a dolphin that carried boys and played with them, and Juvenal of a puppy as a country child's playmate.[2][7] It was used especially of a fellow gambler at dice: Cicero speaks of land shared out comprānsōribus tuīs et collūsōribus, “among your fellow diners and fellow gamblers”.[2][6] An inscription uses it of fellow participants in Salian song and dance.[7]
In the jurists and in the Theodosian Code it took on the sense of one who acts in collusion with another to the harm of a third party.[2][3][7] Medieval writers used it of a playmate, of a fellow mocker, and of a partner at dice: a Lincoln statute of about 1425 complains of someone who plays at dice without stopping and loses twice to suum collūsōrem sīve illūsōrem, “his fellow player or deceiver”.[8][9]
