英文詞源
- calcium
- calcium: [19] Calcium was coined by the English chemist Sir Humphry Davy in 1808 on the basis of Latin calx ‘limestone’ (which is also the ancestor of English calcareous, calculate, calculus, causeway, and chalk). The Latin word probably came from Greek khálix, which meant ‘pebble’ as well as ‘limestone’.
=> calcarious, calculate, causeway, chalk - calcium (n.)
- coined 1808 by English chemist Sir Humphrey Davy (1778-1829), who first succeeded in isolating it, from Latin calx (genitive calcis) "limestone" (see chalk (n.)) + metallic element ending -ium.
