bruit

The noun is derived from Middle English bruit (“commotion, tumult; fame, renown; collective noun for a group of barons”) [and other forms], from Anglo-Norman brut (“commotion, tumult; noise, sounds; fame, renown; hearsay, rumour; collective noun for a group of barons”) and Old French bruit (“commotion, tumult; noise, sounds; fame, renown; hearsay, rumour”) (modern French bruit (“noise; report, rumour”)), a noun use of the past participle of bruire (“to make a noise; to rattle; to roar; to rustle”), from Late Latin brugere, an alteration of Latin rugīre (“to roar”) (the present active infinitive of rugiō (“to bray; to bellow, roar; to rumble”), possibly from Proto-Indo-European *h₁rewg- (“to belch; to roar”)), possibly influenced by Late Latin bragere (“to bray”). The English word is cognate with Catalan brogir (“to roar”); Old Occitan bruir, brugir (“to roar”). The verb is derived from the noun.

Borrowed from French bruit (“noise; report, rumour”), from Old French bruit (“noise; sounds”); see further at etymology 1.
