Etymology

It is inherited from Middle English confederacie,[2][3][4] borrowed from Anglo-Norman confederacie,[2][5][6][7] formed on the stem of Latin cōnfoederō (“to unite in a league”),[8][9] or of cōnfoederātiō (“agreement”), which the American Heritage Dictionary gives as the source.[2][5] The Latin verb is formed from com- (“with, together”) and foederō, from foedus (“a league”),[8] from a suffixed form of Proto-Indo-European *bheidh- (“to trust, confide”).[8] The Anglo-Norman noun is recorded from about 1300, meaning both an alliance and a conspiracy.[7] The English suffix is -acy.[5][6]

Earliest recorded meaning

A union by league or agreement between persons or states for mutual support or joint action: before 1387, in Trevisa's translation of Higden's Polychronicon.[5] Chaucer used it once, in his Boece,[10][11] where Skeat glosses it as "conspiracy".[12]

Semantic evolution

The bad sense, a league for an unlawful purpose, a conspiracy, followed in 1389, in the language of the law;[5] Etymonline notes that in the 17th and 18th centuries the word was often used of a conspiracy against a superior.[8] From the late 14th century it could also mean the body of states so united, first of the leagues of ancient Greece and later of the Netherlands;[8] the OED records this collective sense, now especially a union of states, from 1681.[5] It was used of the United States under the Articles of Confederation (1777–1788);[8][13] since 1861 it has also named the Southern states that seceded, the Confederate States of America.[8][14]
