Pronunciation

  • /məˈsjʊə(ɹ)/, /məˈsjɜː(ɹ)/[1]

Etymology

It is borrowed from Middle French monsieur,[2][3][4][5] literally "my lord",[3][6][7] a compound of mon (“my”) and sieur (“lord”).[2][8][9][10] The French title is recorded from 1297 as Old French monsor, for a man of slightly higher rank.[2] Mon continues the accusative of Latin meus (“my”).[10] Etymonline and Klein take sieur as a shortened form of seigneur;[5][11] Barnhart and Hoad derive it from a reconstructed unstressed form Vulgar Latin *seiōrem, used before a name, from the accusative of senior (“elder”).[4][8][10] It is thus related to sir, sire and monseigneur.[8][12][13]

Earliest recorded meaning

A title put before the name of a French man, at first only of high rank: 1512, in the accounts of the Treasurer of Scotland.[2][3] Barnhart's first record is in the poems of William Dunbar (1500–20),[4] where the OED finds the sense "a Frenchman".[2]

Semantic evolution

In French the word became a courtesy title for any man about 1480, and for the younger brothers of princes at the end of the 15th century;[2] in English Monsieur was also the title of the second son or next younger brother of the King of France, from the 1550s.[2][5] From 1598, in Love's Labour's Lost, it was used alone as a form of address.[2] English speakers often used it humorously or with contempt: Johnson (1755) defined it as "a term of reproach for a Frenchman", quoting Cymbeline,[14] and Monsieur stood for the French nation from 1673 to 1746.[2] Its pronunciation varied: Johnson and the Imperial Dictionary (1850) stressed the first syllable, and Walker (1775) the second;[2] the popular forms mounseer and mossoo reflect English pronunciations.[2][13] Weekley noted that the abbreviation Mons., used by some English writers, is taken in France as a deliberate impertinence.[13]
