英语词汇calcareous的起源、历史背景-英语词源词典

词汇	calcareous
词源	calcareous adj. also calcarious, "of the nature of lime, containing lime, chalky," 1670s, from Latin calcarius "of lime, pertaining to lime," from calx (genitive calcis) "lime, limestone" (see chalk (n.)). The spelling in -eous, which appeared about 1790, is erroneous, influenced by words in -eous from Latin -eus. The etymological sense of calcar-eous would be 'of the nature of a spur.' [OED] Entries linking to calcareous chalk n. Old English cealc "chalk, soft white limestone; lime, plaster; pebble," a West Germanic borrowing from Latin calx (2) "limestone, lime (crushed limestone), small stone," borrowed from Greek khalix "small pebble," which many trace to a PIE root for "split, break up," but Beekes writes that "There is no convincing etymology." Cognate words in most Germanic languages still have the "limestone" sense, but in English transferred chalk to the opaque, white, soft limestone found abundantly in the south of the island. The modern spelling is from early 14c. The Latin word for "chalk" was creta, which also is of unknown origin. With many figurative or extended senses due to the use of chalk marks to keep tracks of credit for drinks in taverns and taprooms, or to keep the score in games. updated on September 25, 2018
