Forms

fédéral (feminine fédérale, masculine plural fédéraux, feminine plural fédérales)[1]

Etymology

It is a learned derivative, from Latin foedus (“treaty of alliance”) (genitive foederis), with the suffix -al.[2][3][4][5] Compare Late Latin foederālis (“relating to a treaty”).[2][3] Littré relates the Latin noun to fīdō (“to trust”);[6] Etymonline traces it to Proto-Indo-European *bʰeydʰ- (“to trust”).[7]

Earliest recorded meaning

It is first recorded in 1783 in the Courrier de l'Europe, meaning “relating to a federation”.[2][3][4]

Semantic evolution

Its derivatives followed during the Revolution: fédéralisme (1789, Robespierre, after an isolated use by Montesquieu), fédéraliste (1792) and fédéraliser (1793).[4][3]

The plural noun les fédéraux named the soldiers and supporters of the Northern states in the American Civil War; the TLFi takes it from Littré (1865), while the DHLF dates it to 1883 and treats it as borrowed from English.[2][3][6] Through a further borrowing it also names agents of the United States federal police.[3] In the 20th century the adjective came to be used of a sporting or trade-union federation.[8] In Canada it is opposed to provincial and in Switzerland to cantonal.[9]

The English word federal had its political sense “formed by agreement among independent states” by 1707.[7][2]
