Pronunciation

Forms

baron m (plural barons, feminine baronne)[1] Old French nominative ber (also bers), oblique baron.[2][3][4]

Etymology

As a feudal title it is borrowed from Frankish *barō (“free man”).[2][5][6][7][4][8] The Salic Law has the compound sacebaro, a royal official below the count who collected judicial fines;[4][2] Rey connects its first part with Old Norse saka (“to accuse”) and its second with berja (“to strike, kill”), from the root Proto-Indo-European *bʰer- (“to cut”).[4]

Before the Franks invaded Gaul, Germanic soldiers in the Roman armies had already brought the word into Latin with its proper sense, free man or warrior: Isidore of Seville has Late Latin barō (“mercenary”), and the Salic Law uses it for a man as opposed to a woman.[2][4] Wiktionary therefore takes the Old French oblique case baron as inherited from the Latin accusative barōnem, with the nominative ber as the regular outcome of the Latin nominative.[1] The Old Occitan nominative was likewise bar.[2][3]

Spanish varón (“man, male”) and Portuguese varão keep the old sense; Italian barone was borrowed from French.[4][2]

Earliest recorded meaning

It is first recorded in the 10th century in the Vie de saint Léger.[2][6] In the Chanson de Roland (1080) ber and baron mean a brave, worthy man and a great lord: Seigneur baron, à Charlemagne irez.[4][3]

Semantic evolution

In Old French the word meant a brave man, a saint, then a husband (end of the 12th century), a sense kept in Picard and still listed in the 17th and 18th centuries.[4][3] In the feudal period it named a great lord of the realm, the direct vassal of the king, and any noble of high rank, with a note of valour; from the 12th century it was also the holder of a barony, below the count.[4] Since the Revolution it is only a title of nobility.[4][7]

By analogy it came to mean a powerful man (19th century), as in les barons de la finance, and in the 20th century the old sense “great vassal” was taken up in politics (les barons du gaullisme).[4][3][7] In slang, then in familiar use, a baron is an accomplice who poses as a customer so that the swindler can fool the real ones (1901); Bob dates it from 1894.[4][7][9]

Usage notes

The cooking term baron (baron d'agneau, the two legs and the loin of a lamb) is dated 1839 by the Grand Robert and 1928 by Rey; it may come from the English baron of beef, and a link with the title is doubtful.[5][4][7] Another baron, a very large glass of beer in some Paris cafés (20th century), is an uncertain metaphor from one of these.[5]
