Word Origin & History

talus  (1)
"anklebone," 1693, from L. talus "ankle, anklebone, knucklebone" (pl. tali), related to L. taxillus "a small die, cube" (they originally were made from the knucklebones of animals).

talus  (2)
"slope," 1645, from Fr. talus (16c.), from O.Fr. talu "slope" (12c.), probably from Gallo-Romance *talutum, from L. talutium "a slope or outcrop of rock debris," possibly of Celtic origin (cf. Breton tal "forehead, brow"). OED, however, suggests derivation from root of talus (1) in the sense of "heel" which developed in its Romanic descendants. Mainly used of military earthwork at first; meaning "sloping mass of rocky fragments that has fallen from a cliff" is first recorded 1830.
