- zinc (n.)
- 1650s, zinke, from German Zink, perhaps related to Zinke "prong, point;" said to have been used first by Paracelsus (c. 1526) on analogy of the form of its crystals after smelting. Zinke is from Old High German zint "a point, jag," from Proto-Germanic *teng- "tine" (cognates: Old Norse tindr "point, top, summit," Old English tind "prong, spike"), from PIE *denk- "to bite." Spelling with -c- is from 1813, from French influence.
