From Middle English bosten, from bost (“boast, glory, noise, arrogance, presumption, pride, vanity”), probably of North Germanic origin, ultimately from Proto-Germanic *bausuz (“inflated, swollen, puffed up, proud, arrogant, bad”). Cognate with Scots bost, boist (“to threaten, brag, boast”), Anglo-Norman bost (“ostentation”) (from Germanic). Related to Norwegian baus (“proud, bold, daring”), dialectal German baustern (“to swell”), German böse (“evil, bad, angry”), Dutch boos (“evil, wicked, angry”), West Frisian boas (“bad, wicked, angry, shrewd, clever”). Compare also dialectal Norwegian bausta, busta (“to rush onward, make a noise”). Possible doublet of boost. Compare typologically puffy, Russian напы́щенный (napýščennyj), наду́тый (nadútyj).
When used to mean 'possess', the verb is transitive; when used to mean 'brag', it is often intransitive and takes 'of' or 'about'.
