Uxorious \uk-SOR-ee-us\ or \ug-ZOR-ee-us\ , adjective;
1. Excessively fond of, or submissive to a wife
This word dates to the 1590's and is borrowed from Latin uxorious ("of or pertaining to a wife"), which comes from uxor ("wife") of unknown origin. Uxorial is first attested around 1800 and is sometimes used in the same sense of uxorious even though its definition is "relating to a wife or wives". Uxoricide as a verb meaning "the murder of one's wife" dates to 1854 and as a noun ("one who kills his wife") dates to 1860.
Since we're on the topic: pussy-whipped is first attested in 1953.
