n.Old English tin, from Proto-Germanic *tinom (cf. Middle Dutch and Dutch tin, Old High German zin, German Zinn, Old Norse tin), of unknown origin, not found outside Germanic. Other Indo-European languages often have separate words for “tin” as a raw metal and “tin plate;” e.g. French étain, fer-blanc. Pliny refers to tin as plumbum album “white lead,” and for centuries it was regarded as a form of silver debased by lead. The chemical symbol Sn is from Late Latin stannum (see stannic). Tin-type in photography is from 1864. Tin ear “lack of musical discernment” is from 1909. Tin Lizzie “early Ford, especially a Model T,” first recorded 1915. n. Symbol Sn
- A malleable metallic element used to coat other metals to prevent corrosion. Atomic number 50.
- A malleable, silvery metallic element that occurs in igneous rocks. It has a crystalline structure and crackles when bent. Tin is used as an anticorrosion agent and is a part of numerous alloys, including bronze. Atomic number 50; atomic weight 118.71; melting point 231.89°C; boiling point 2,270°C; specific gravity 7.31; valence 2, 4. See Periodic Table. See Note at element.
