capon (n.)

"a castrated cock," late Old English capun, from Latin caponem (nominative capo) "castrated cock" (also source of French chapon, Spanish capon, Italian cappone), perhaps from a verb meaning "to strike off," from PIE root *(s)kep- "to cut" (see hatchet (n.)). Probably reinforced in Middle English by cognate Old North French capon.
