Etymonline
Word Origin & History
open
O.E. open "not closed down, raised up" (of doors, gates, etc.), also "uncovered, bare; plain, evident," from P.Gmc. *upana, lit. "put or set up" (cf. O.N. opinn, Swed. öppen, Dan. aaben, O.Fris. epen, O.H.G. offan "open"), from PIE *upo "up from under, over" (cf. L. sub, Gk. hypo; see
sub-). Related to up, and throughout Gmc. the word has the appearance of a pp. of *up (v.), but no such verb has been found. The source of words for "open" in many I.E. languages seems to be an opposite of the word for "closed, shut" (e.g. Goth. uslukan). Of shops, etc., "available for business," it dates from 1824. Transf. sense of "candid" is attested from 1513. The verb was O.E. openian, but etymology suggests the adj. was older. Open up "cease to be secretive" is from 1921. The noun meaning "public knowledge" (esp. in out in the open) is attested from 1942; the sense of "an open competition" is from 1926, originally in a golf context. Open-handed "liberal, generous" is from 1601. Open door in ref. to international trading policies is attested from 1856. Open season is first recorded 1896, of game; and figuratively 1914 of persons. Open book in the fig. sense of "person easy to understand" is from 1853. Open house "hospitality for all visitors" is first recorded 1824. Open-and-shut "simple, straightforward" first recorded 1841 in New Orleans. Open marriage, one in which the partners sleep with whomever they please, is from 1972. Open road (1817, Amer.Eng.) originally meant a public one; romanticized sense of "traveling as an expression of personal freedom" first recorded 1856, in Whitman.
