talon: [14] Latin tālus meant ‘ankle’ (it was probably a borrowing from Celtic – Irish has sal ‘talon’). From it was derived Vulgar Latin *tālō ‘heel, spur’, which passed into English via Old French talon. In English its meaning evolved via ‘heel of an animal’ and ‘bird of prey’s claw’ to ‘claw’ in general.
