"breast or rib-meat of an animal," mid-14c., brusket, perhaps from Old French bruschet, with identical sense of the English word, or from Old Norse brjosk "gristle, cartilage" (related to brjost "breast") or Danish bryske or Middle High German brusche "lump, swelling;" from PIE *bhreus- "to swell, sprout" (see breast (n.)).
mid-15c., brousen, "feed on buds, eat leaves or twigs from" trees or bushes, from Old French broster "to sprout, bud," from brost "young shoot, twig, green food fit for cattle or deer," probably from Proto-Germanic *brust- "bud, shoot," from PIE *bhreus- "to swell, sprout" (see breast (n.)). It lost its -t in English perhaps on the mistaken notion that the letter was a past-participle inflection. The figurative extension to "peruse" (books) is 1870s, American English.
