Pronunciation

  • /kəˈluːʒən/[1]

Etymology

It is inherited from Middle English collusioun,[2][3] borrowed from Old French collusion[4][5][6] and directly borrowed from Latin collūsiō (“a playing together; collusion”),[4][5][7][2] from the past participle of collūdō (“to play together; to collude”),[7][8] formed from com- (“with, together”) and lūdō (“to play”), from lūdus (“game, play”).[4][5][8] The Anglo-Norman word is recorded from 1291–92.[9] The verb collude was borrowed from the same Latin verb in 1525.[5][8]

Earliest recorded meaning

In law, a secret agreement between persons to get round the law or to gain an end by fraud: 1389, in the London guild returns.[2][5] The OED's first example is from Chaucer's Lak of Stedfastnesse (c. 1397), the only time Chaucer uses it.[6][10]

Semantic evolution

The OED notes that the literal sense "a playing together", given in Blount's Glossographia (1656), is not found in use in Latin or English: the word meant secret, underhand agreement from the start.[6] Weekley explains the Latin as playing into one another's hands.[11] The specifically legal sense, an agreement between apparent opponents in a lawsuit to deceive the court or defraud a third party, is recorded from 1509–10,[6] and Johnson (1755) quoted Cowell's definition of it as a deceitful compact between two or more to bring an action against each other for an evil purpose.[12] From 1581 to 1659 the word could also mean a trick or ambiguity in words or reasoning.[6]
