9 Grammatical Pitfalls
Latinate spelling preferred in British English for most uses of disk (q.v.). American English tends to use it in the musical recording sense; originally of phonograph records, recently of compact discs. Hence, discophile "enthusiast for gramophone recordings" (1940).
American English preferred spelling, 1660s, "round flat surface," from Latin discus "quoit, discus, disk," from Greek diskos, from dikein "throw," from PIE *dik-skos-, from root *deik- "to show, pronounce solemnly; also in derivatives referring to the directing of words or objects" [Watkins].
