Forms

marteau m (plural marteaux)[1] Old French martel (plural marteals, martiaus), also marteil (1206); the singular marteau is found from about 1380.[2][3][4]

Etymology

It is inherited from Old French martel, inherited from Late Latin martellus (in Isidore of Seville and the Latin glossaries), from martulus, an altered form of marculus (“hammer”).[2][5][6] This is a hypercorrect form, made in reaction to the popular change of -culus to -clus, after the model of vetulus (“old”) beside Vulgar Latin veclus.[2][7] The latter is the diminutive of marcus, which Bloch and Wartburg and Rey regard as a late form made from it;[7][5] Rey relates the word to malleus (“hammer”).[5] The modern singular was formed from the Old French plural marteaus.[1][3]

Cognate with Italian martello, Old Occitan martel, Catalan martell, Spanish martillo and Portuguese martelo.[8][4]

Earliest recorded meaning

About 1140 the Voyage de Charlemagne has the plural marteals for iron tools used to beat and forge metal.[2][5]

Semantic evolution

Special kinds followed, such as the marteau à maçon (1389) and marteau de tapisserie (1453), and entre le marteau et l'enclume “between the hammer and the anvil” is found in 1206.[2][5] By likeness of use it named many striking tools from Middle French on: the forester's marking hammer (1302), a door knocker (14th century), a war hammer (1391), the striker of a clock (1453), the hammer of a piano (1751) and the auctioneer's hammer (1848).[2][5] The small bone of the ear is so called from 1611, paired with enclume.[5]

Avoir un coup de marteau “to be mad” is in Ronsard (1587), whence the familiar adjective être marteau (1889; 1882 according to Bloch and Wartburg).[2][5][7] In sport the word names the throwing hammer (1900) and the event itself.[5]
