英文词源

screen: screen: [15] Screen goes back ultimately to a Frankish *skrank ‘barrier’, a distant ancestor of German schrank ‘cupboard’. This was taken over into Old Northern French as escran, and it was a variant form of this, escren, that became English screen.
screen (n.): mid-14c., "upright piece of furniture providing protection from heat of a fire, drafts, etc.," probably from a shortened (Anglo-French? compare Anglo-Latin screna) variant of Old North French escren, Old French escran "fire-screen" (early 14c.), perhaps from Middle Dutch scherm "screen, cover, shield," or Frankish *skrank "barrier," from Proto-Germanic *skerm- (cognates: Old High German skirm, skerm "protection," from PIE *(s)ker- (1) "to cut" (see shear (v.)).

Meaning "net-wire frame used in windows and doors" is recorded from 1859. Meaning "flat vertical surface for reception of projected images" is from 1810, originally in reference to magic lantern shows; later of movies. Transferred sense of "cinema world collectively" is attested from 1914; hence screen test (1918), etc. Screen saver first attested 1990. Screen printing recorded from 1918.
screen (v.): "to shield from punishment, to conceal," late 15c., from screen (n.). Meaning "examine systematically for suitability" is from 1943; sense of "to release a movie" is from 1915. Related: Screened; screening.
