- boast
[boast 词源字典] - boast: [13] The immediate source of boast appears to be Anglo-Norman bost, but where it came from before that is far from clear; German dialect bauste(r)n ‘swell’ has been compared, suggesting that it could be of Germanic origin. To begin with it meant ‘loud or threatening talk’ as well as ‘bragging’.
[boast etymology, boast origin, 英语词源] - boast (n.)
- mid-13c., "arrogance, presumption, pride, vanity;" c. 1300, "a brag, boastful speech," from Anglo-French bost "ostentation," probably via Scandinavian (compare Norwegian baus "proud, bold, daring"), from Proto-Germanic *bausia "to blow up, puff up, swell" (cognates: Middle High German bus "swelling," dialectal German baustern "to swell;" Middle Dutch bose, Dutch boos "evil, wicked, angry," Old High German bosi "worthless, slanderous," German böse "evil, bad, angry"), from PIE *bhou-, variant of root *beu-, *bheu- "to grow, swell" (see bull (n.2)).
The notion apparently is of being "puffed up" with pride; compare Old English belgan "to become angry, offend, provoke," belg "anger, arrogance," from the same root as bellows and belly (n.). Related: Boasted; boasting. An Old English word for "boasting" was micelsprecende, "big talk." - boast (v.)
- early 14c., "to brag, speak arrogantly;" from the same source as boast (n.). Related: Boasted; boasting.
