Morphology

pin + bone

The compound combines 'pin' (a small, pointed object) with 'bone', so a learner who knows both words can reasonably infer it denotes a small, pin‑like bone found in meat. However, the precise technical location in the sirloin (between the flat bone and the porterhouse) is specialized butchery knowledge that is not predictable from the constituents alone. Because the general sense is derivable but the specific referent is technical, the expression is only partially transparent.

Etymology

Pin bone comes from butchers naming a small, thin bone that looks like a pin set between bigger bones in the sirloin. So, the name now means that specific 'part of the sirloin' where the tiny bone sits, the piece butchers and chefs prepare.
