[Noun]  | "in*cus" | \ ˈiŋ-kəs \

1: the middle bone of a chain of three small bones in the ear of a mammal —called also anvil

Origin: 1615 ;

 Borrowed from New Latin incūd-, incūs, going back to Latin, "anvil," from in- {see: |in-:2|in-:2} + -cūd-, -cūs, root noun from the stem of cūdere "to beat, strike, hammer" ;

  * Note : The Latin name incūs "anvil" was first applied to the bone from its resemblance to an anvil by Andreas {vesalius|Vesalius:b}, in De humanis corporis fabrica libri septem (Basil, 1543), pp. 34-35; for details see: C.D. O'Malley and Edwin Clarke, "The discovery of auditory ossicles," Bulletin of the History of Medicine, vol. 35, no. 5 (September-October, 1961), pp. 419-41.
