Latin : ad, to + hominem, accusative of hom┼Ź, man.
(American Heritage® Dictionary of the English Language, Fourth Edition)
Shortened from the Latin expression argumentum ad hominem, argument at the man (man as in a human being, not man as a male). From argumentum (meaning "argument") + ad (meaning "to" or "at") + hominem, the accusative singular of homo (meaning "man"). It can also mean attacking the messenger. (Wiktionary)
