Pronunciation

  • /mɑ̃.tœʁ/[1]

Forms

menteur m (plural menteurs, feminine menteuse)[1] Old French menteür, menteor, menteeur, with the nominative menterre and the feminine menteresse.[2][3][4] The feminine menteuse is found from 1594 and replaced menteresse in the 17th century.[2][5]

Etymology

It is formed from French mentir + -eur, first as menteür in 1155.[2][6][3] The verb is from Latin mentior (“to lie”).[7]

The Old French nominative menterre (feminine menteresse) may go back to Vulgar Latin *mentītor, formed on the supine of the verb but attested only late.[2][7][1] Littré explained mentiere as the nominative and menteor as the oblique case of that Latin noun.[8] The same Latin noun is continued by Italian mentitore, Catalan mentidor and Portuguese mentidor.[9][8] The French derivative replaced the old nominative.[5]

Earliest recorded meaning

In Wace's Brut (1155) menteür is a man who tells lies.[2][5] The feminine menteresse, in the sense “perjurer”, is older: Wace already uses it in his Life of St Margaret (1130–1140).[2]

Semantic evolution

The adjective, “lying”, is found about 1200 in the songs of the Châtelain de Coucy, who speaks of a faus druz menteor “false, lying lover”;[2][8] from 1306 it is also used of things, “false, made up”.[2] Menteresse lasted until the early 17th century and is still used in some regional speech.[2][5]

The comparison menteur comme un arracheur de dents is recorded from 1668;[3] Littré explains it by the tooth-puller's promise that his patients will feel no pain.[8] In hunting a chien menteur is a dog that hides the scent to get ahead or gives tongue falsely.[8] Slang made la menteuse the tongue (1827), menteur a newspaper (1899) and la menteuse the political press (1930s).[2][5]
