Word Origin and History for ounce
ounce
"unit of weight," early 14c., from O.Fr. unce (12c.), from L. uncia "one-twelfth part" (of a pound, foot, etc.), from L. unus "one" (see one). The L. word had been adopted in O.E. as ynce (see inch). It was one-twelfth of a pound in the Troy system of weights, but one-sixteenth in avoirdupois. Abbreviation oz. is from It. onza. Also used in M.E. as a measure of time (7.5 seconds) and length (about 3 inches).
ounce
"wildcat," c.1300, from O.Fr. once, from lonce, with l- mistaken as definite article, from V.L. *luncea, from L. lyncea "lynx-like," from lynx (see lynx). Originally the common lynx, later extended to other wildcats, now mainly used of the mountain-panther or snow leopard of Asia.
