Orient - c.1375, from L. orientem (nom. oriens) "part of the sky where the sun rises," originally "rising" (adj.), prp. of oriri "to rise." The verb is c.1730s, originally "to arrange facing east," from Fr. s'orienter "to take one's bearings," lit. "to face the east" (also the source of Ger. orientierung), from O.Fr. orient "east," from L. orientum. Meaning "determine bearings" first attested 1842. Oriental (adj.) is 14c. from O.Fr. oriental, from L. orientalis "of the east," from orientem. Orientation is from 1839 and originally meant "arrangement of a building, etc., to face east or any other specified direction;" sense of "determine one's bearings" is from c.1870.
