As the vocabulary word fèvre ‘smith’ was replaced by forgeron, the meaning of the old word became opaque, and the surname was reinterpreted as if it were La fève, from fève ‘(fava) bean’. Lefevre is the most common name in French Canada; great numbers of them migrated to the US, where many adopted the name Bean, in the belief that it was a translation of Lefèvre. See also Lafave.

Originally an English pet name BEAU means "handsome," derived from the French word, beau, meaning "beautiful." Later, in the 19th century, it was used as a word meaning "admirer" or "sweetheart." Its use as a forename seems to have been due to Wren's novel Beau Geste (1924) and the character Beau Wilkes in Mitchell's Gone With the Wind (1936).Â

English : from the Middle English nickname Bere meaning ‘bear’ (Old English bera, which is also found as a byname), or possibly from a personal name derived from a short form of the various Germanic compound names with this first element. Compare for example Bernhard. The bear has generally been regarded with a mixture of fear and amusement because of its strength and unpredictable temper on the one hand and its clumsy gait on the other, and in the medieval period it was also thought to typify the sins of sloth and gluttony. All these characteristics are no doubt reflected in the nickname. Throughout the Middle Ages the bear was a familiar figure in popular entertainments such as bear baiting and dancing bears.English : variant spelling of the habitational name Beer.Probably a translation of cognates of 1 in other languages, for example German Baer, and also an Americanized spelling of German Bahr.
