orbit: [16] Orbit comes from Latin orbita. This was a derivative of the noun orbis, which originally meant ‘circle, disc’. It was applied metaphorically to a number of circular things, including the ‘circular path of a satellite’ (from which the main meaning of orbit comes) and also the ‘eye socket’, and eventually came to be applied to ‘spheres’ as well as ‘circles’ – whence English orb [16].
=> orb - orbit (n.)
- late 14c., "the eye socket," from Old French orbite or directly from Medieval Latin orbita, transferred use of Latin orbita "wheel track, beaten path, rut, course, orbit" (see orb). Astronomical sense first recorded 1690s in English; it was in classical Latin, revived in Gerard of Cremona's translation of Avicenna. The Old English word for "eye socket" was eaghring.
- orbit (v.)
- 1946, from orbit (n.). Related: Orbited; orbiting.
