Middle English brawne, from Old French braon (“slice of meat, fleshy part, buttock”), from Frankish *brādon, accusative form of *brādo (“roasted meat, ham”), from Proto-Germanic *brēdô (“meat, roast”), from Proto-Indo-European *bhre- (“to burn, heat”), from Proto-Indo-European *bureue- (“to boil, bubble, burn”). Akin to Old High German brāto (“tender meat”) (German Braten (“roast”)), Old English brǣd (“flesh, meat”), Old Norse bráð (“raw meat”).
