schab.

Unknown. Compare with dialectal chab, chaba, chaby pl, skaby pl (“rib(s); a hollow in the body near the clavicle (in humans), the sacrum (in animals); lean meat; cattle waste; skinny old animal”), chabor, chabora (“bone; pig's shoulder; skinny animal”), chrabury pl (“bones without meat”), chaber (“bone”), chabry pl (“scrap of meat”); Kashubian schabë pl (“poultry skeleton”), chaba (“skinny cow”), chaber (“poultry back bone peeled of meat”). Equivalents outside Poland: Middle Russian схабы pl (sxaby), Russian схаб (sxab, “costal part”), Old Ruthenian схабъ (sxab, “pork meat”), Ukrainian схаб (sxab, “piece of pork or lamb from the costal part of the carcass”), Belarusian схаб (sxab), Moravian Czech chabanina (“dry, poor meat”) (> Polish chabanina?), maybe Russian кабани́на (kabanína, “wild boar meat”), Ukrainian кабани́на (kabanýna) (> Polish kabanina). Brückner suggested chabina (“rod, bar”) as a possibly related word. Moravian chabanina is usually connected to Czech chabý (“feeble, flimsy, weak”) from Proto-Slavic *xabъ. Russian/Ukrainian кабани́на is ultimately of Turkic origin (see Russian кабан (kaban), Polish kaban).
