Word Origin and History for ounce
unit of weight, early 14c., from Old French once, unce, a measure of weight or time (12c.), from Latin uncia "one-twelfth part" (of a pound, foot, etc.), from Latin unus "one" (see one). The Latin word had been adopted in Old English 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 older Italian onza. Also used in Middle English as a measure of time (7.5 seconds) and length (about 3 inches).
"wildcat," c.1300, from Old French once "lynx" (13c.), from lonce, with l- mistaken as definite article, from Vulgar Latin *luncea, from Latin 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.
