Chine

chine \ˈchīn\ noun: 1. backbone, spine, 2. a cut of meat including all or part of the backbone, 3. the intersection of the bottom and the sides of a flat or V-bottomed boat

Etymology: Middle English, from Anglo-French eschine, of Germanic origin; akin to Old High German scina shinbone, needle

The sound of the word chine makes me think of chyme. Try using both words in one sentence (and have that sentence make sense!).
