bold

bold: [OE] In Old English, bold meant simply ‘brave’; the modern connotations of immodesty or presumptuousness do not seem to have developed until the 12th century. The word goes back to a prehistoric Germanic *balthaz, based ultimately, it has been speculated, on Indo- European *bhel- ‘swell’ (the psychological link through ‘being puffed up’ via ‘a(chǎn)dventurous courage’ to ‘a(chǎn)udacity’ is scarcely far-fetched). If this is so it would mean bold is related to bellows, belly, billow, bolster, and possibly bellow and bell. The notion of impetuosity is perhaps retained in the related German bald ‘soon’.
=> bell, bellows, belly, billow, bolster

bold (adj.)

Old English beald (West Saxon), bald (Anglian) "bold, brave, confident, strong," from Proto-Germanic *balthaz (cognates: Old High German bald "bold, swift," in names such as Archibald, Leopold, Theobald; Gothic baltei "boldness;" Old Norse ballr "frightful, dangerous"), perhaps from PIE *bhol-to- suffixed form of *bhel- (2) "to blow, swell" (see bole).

Of flavors (coffee, etc.) from 1829. The noun meaning "those who are bold" is from c. 1300. Old French and Proven?al baut "bold," Italian baldo "bold, daring, fearless" are Germanic loan-words.
