Pronunciation

Forms

ferrer[1] Old French ferer and, in Anglo-Norman, fereer beside ferrer.[2][3]

Etymology

It is inherited from Vulgar Latin *ferrō (“to fit with iron”),[4][5][6] which Rey derives from Classical Latin ferrātus (“fitted with iron, containing iron”), a derivative of ferrum (“iron”).[7] Wiktionary allows that the Old French verb may also have been formed directly on fer.[1]

Cognate with Italian ferrare, Occitan ferrar, Catalan ferrar, Spanish herrar and Portuguese ferrar.[4][3][8] Meyer-Lübke also lists Romanian înfiera and a Basque borrowing.[8]

Earliest recorded meaning

It is first found about 1140 in the Pèlerinage de Charlemagne, meaning to fit or strengthen something with iron or another metal, and in the same text of fitting a horse's hooves with shoes.[9]

Semantic evolution

Besides fitting with iron and shoeing animals, the medieval verb meant to put someone in irons (before 1233), a sense that came back in the 19th century for the chaining of convicts (1828–29, Vidocq).[9][7] The participle ferré described a road covered with broken stone (1176–81, Chrétien de Troyes), the idea being hardness; in voie ferrée (1851) it is the metal of the rails that is meant.[9][7] By a metaphor of hardness ferré also came to mean “difficult”, then “wise, skilful” (about 1450) and “well versed” in être ferré sur a subject.[7][9]

Figurative phrases with horseshoes appeared in Middle French: se laisser ferrer (about 1462, Cent Nouvelles nouvelles) and ferrer la mule (about 1535).[9][10] In angling ferrer le poisson means to drive the hook into a fish that has bitten (before 1856).[7][11]
