köken: Disputed. Possibly by assimilation from Hebrew בָּרוּךְ הַבָּא (barúkh habá, “blessed (be) who comes”), a collocation occurring in Psalm 118:26 and an interjection meaning “welcome” in Modern Hebrew. An alternative theory holds that the origin is onomatopoeic. In regards to the semantic evolution to “noisy meeting”, compare ramdam, sabbat.
Un brouhaha, une tempête d’exclamations accueillit ces paroles.
