canopy (n.)youdaoicibaDictYouDict[canopy 词源字典]
late 14c., from Old French conope "bed-curtain" (Modern French canapé), from Medieval Latin canopeum, dissimilated from Latin conopeum, from Greek konopeion "Egyptian couch with mosquito curtains," from konops "mosquito, gnat," which is of unknown origin. The same word (canape) in French, Spanish, and Portuguese now means "sofa, couch." Italian canape is a French loan word.[canopy etymology, canopy origin, 英语词源]
curtain (n.)youdaoicibaDictYouDict
c. 1300, from Old French cortine "curtain, tapestry, drape, blanket," from Late Latin cortina "curtain," but in classical Latin "round vessel, cauldron," from Latin cortem (older cohortem) "enclosure, courtyard" (see cohort). The confusion apparently begins in using cortina as a loan-translation for Greek aulaia ("curtain") in the Vulgate (to render Hebrew yeriah in Exodus xxvi:1, etc.) because the Greek word was connected to aule "court," perhaps because the "door" of a Greek house that led out to the courtyard was a hung cloth. The figurative sense in curtain call is from 1884. Curtains "the end" is 1912, originally from stage plays. An Old English word for "curtain" was fleonet "fly-net."
