tobillo
/toˈbiʝo/ · B1 · noun · m
ankle
🦶 From Latin tuber, lump: the ankle is the bony lump just above your foot
Tobillo comes from Vulgar Latin tubellum, a little lump, from tuber, a swelling (the same root as tuber and tuberculosis). It names the knob of bone on each side of your ankle. Say it toe-BEE-yo: it starts with toe, and toes are close by.
