cadre

Etymology

It is borrowed from French cadre (“frame, border of a picture”),^[2][3][4] from Italian quadro (“four-sided shape, square”),^[2][5][6][4] from Latin quadrum (“a square”);^{[5][6][4][3][7]} Hoad, Klein and the Shorter Oxford give the adjective quadrus (“square”).^{[8][9][10][11]} The Latin word is related to quattuor (“four”),^[3][4] from Proto-Indo-European *kwetwer- (“four”).^[3][5] In French the word meant a frame from 1549, the complement of officers of an army from 1796, the framework of a literary work from 1803 and a body of employees from 1840.^[2] Etymonline explains the military sense as a detachment forming the skeleton of a regiment,^[3] and Dictionary.com as the framework into which temporary personnel are fitted.^[12] Merriam-Webster Unabridged takes the communist sense as probably from Russian, which had borrowed the French word.^[6]

Earliest recorded meaning

The complement of officers of a regiment: 1796, in Bell's Weekly Messenger, in the OED, revised in 2024.^[2] Etymonline dates the military sense to 1851 and the sense "framework" to 1830,^[3] and Merriam-Webster Unabridged gives 1763 as its first date.^[6]

Semantic evolution

The military sense soon broadened to a permanent core of trained personnel that forms a nucleus for expansion (1797, in Wolfe Tone's writings).^[2] The first edition of the OED (1888) noted that after the Indian Rebellion of 1857 the cadres of disbanded native regiments were kept in the Indian Army List to regulate promotions, and that the word was constantly used in this sense in the parliamentary debates on merging the Indian and British armies.^[2] Walter Scott used it for a framework or scheme in his introduction to The Lay of the Last Minstrel (before 1832).^[2][4] In the 20th century the word passed to a group of trained specialists (1925), to a group of workers promoting the Communist Party, or a member of one (1928), and in China to an office-holder of the Party, government or army (1952).^[2][3] From the 1950s it could mean any group sharing a belief or interest, and in 1971 a set of similar things.^[2] Collins records its use for a group of revolutionaries or political activists, and for one member.^[7]
