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