[Italian, from Latin, plate (from the incrustation on ancient metal plates and dishes); see paten.]Usage Note: Most English words borrowed from Italian follow the stress pattern of that language and are stressed on the second-to-last syllable. There are many exceptions to this rule, however, and among them is the traditional pronunciation of patina, which has emphasis on the first syllable, so it rhymes with the phrase sat in a. This pronunciation remains the preferred pronunciation in Britain. But patina also developed a pronunciation that follows the pattern of other -ina words in English, such as cantina. In the 2009 survey, not only did 90 percent of the Usage Panel find this newer pronunciation acceptable, 60 percent preferred it.patina (ˈpætɪnə) n, pl -nas1.

Translations
patina
patina (păt`ənə), coating of carbonate of copper on articles of copper or bronze, formed after long exposure to a moist atmosphere or burial in the earth. Although commonly green, patina varies in color and consistency; it may be red, brown, black, blue, or gray, or it may be smooth, glossy, or crusty. It may be imitated by a number of oxidation processes. The term has been extended to include the film formed on metals, pottery, marble, and other materials by exposure and to the mellow surface acquired by furniture with time and waxing.PatinaA greenish-brown crust produced by oxidation that forms on the surface of copper and bronze, often multicolored and considered decorative; any thin oxide film which forms on a metal or other material.Patina a film ranging from green to cinnamon in color that forms on the surface of copper, bronze, and brass articles. A patina results from the natural corrosion of the metal or from patination—that is, heating or processing with oxidizing agents. A patina formed by the latter method is used to protect works of art and for decorative purposes. Roman artists were the first to recognize patina as a sign of beauty through aging. The term “patination” is also used to designate the process whereby articles not made from copper alloys, for example, plaster-of-paris sculptures, are tinted bronze. patina[′pat·ən·ə or pə′tē·nə] (geology) A thin, colored film produced on a rock surface by weathering. (metallurgy) The greenish product, usually basic copper sulfate, formed on copper and copper-rich alloys as a result of prolonged atmospheric corrosion. patina, patination1.
