brisket (n.)

"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.)).
