Pronunciation

Etymology

It is probably a clipping from English of caddie, or of its variants caddee and cadee,[2][3][4][5][6][7] which come from French cadet;[2] the Shorter Oxford, the Oxford Dictionary of English and Cresswell allow either caddie or cadet,[8][9][10] and Etymonline derives it from cadet.[11] Barnhart describes caddie, an errand boy or porter, as a Scottish variant of cadet, recorded from 1730.[12][13] Cadet is from Occitan capdet (“captain, chief”), a Gascon word, from Medieval Latin capitellum (“little head”), a diminutive of Latin caput (“head”).[11][10]

Earliest recorded meaning

A passenger picked up by a stagecoach driver for part of the route without a booking, who paid the driver privately: 1790, in Kearsley's Pocket Ledger.[2][13][9] The OED thinks that the sense "unskilled helper", recorded later, is probably the original one.[2]

Semantic evolution

The early cads were humble helpers: Etymonline dates the word for servants to 1730,[11] and the OED records it for a man or boy who did unskilled work for a tradesman from 1801 and for a coach driver's assistant or omnibus conductor from 1820.[2][8] The English Dialect Dictionary still has it for an odd-job man or messenger in Lincolnshire and the West Midlands.[14] At Eton, Oxford and other schools and universities it became a contemptuous name for the townspeople (1825),[2][3] part of the "town-and-gown" rivalry,[10] while at Cambridge the word for them was snob.[11][15] Green's Dictionary of Slang records cad for an ill-mannered lout from 1821.[16] The modern sense, a man who behaves dishonourably, especially towards women, is recorded from 1831 in the OED;[2] Etymonline and Barnhart date it to 1838.[11][13] Collins now labels the word old-fashioned.[7]
