Word Origins Dictionary
- boisterous (adj.)



[boisterous 词源字典] - late 15c., unexplained alteration of Middle English boistous (c. 1300) "rough, coarse (as of food), clumsy, violent," which is of unknown origin, perhaps from Anglo-French bustous "rough (road)," which is perhaps from Old French boisteos "curved, lame; uneven, rough" (Modern French boiteux), itself of obscure origin. Another guess traces it via Celtic to Latin bestia. Used of persons from 1560s. Related: Boisterously; boisterousness.[boisterous etymology, boisterous origin, 英语词源]
