| tin | 1. <chemistry> An elementary substance found as an oxide in the mineral cassiterite, and reduced as a soft white crystalline metal, malleable at ordinary temperatures, but brittle when heated. It is not easily oxidized in the air, and is used chiefly to coat iron to protect it from rusting, in the form of tin foil with mercury to form the reflective surface of mirrors, and in solder, bronze, speculum metal, and other alloys. Its compounds are designated as stannous, or stannic. Symbol Sn (Stannum). Atomic weight 117.4. 2. Thin plates of iron covered with tin; tin plate. 3. Money. <chemistry> Block tin, stannous chloride, used as a mordant in dyeing and calico printing. Tin penny, a customary duty in England, formerly paid to tithingmen for liberty to dig in tin mines. Tin plate, thin sheet iron coated with tin. Tin pyrites. See Stannite. Origin: As. Tin; akin to D. Tin, G. Zinn, OHG. Zin, Icel. & Dan. Tin, Sw. Tenn; of unknown origin.

| tinamou | <ornithology> Any one of several species of South American birds belonging to Tinamus and allied genera. In general appearance and habits they resemble grouse and partridges, but in anatomical characters they are allied to the ostriches and other struthious birds. Their wings are of moderate length, and they are able to fly a considerable distance. Origin: From the native name: cf. F. Tinamous. Source: Websters Dictionary (01 Mar 1998) |
