- astronomy (n.) c. 1200, "astronomy, astrology, scientific or occult study of heavenly bodies," from Old French astrenomie "astronomy, astrology," from Latin astronomia, from Greek astronomia, abstract noun from astronomos, literally "star-regulating," from astron "star" (from PIE root *ster- (2) "star") + nomos "arranging, regulating; rule, law," from PIE root *nem- "assign, allot; take." Perhaps originally with reference to mapping the constellations or movements of planets.
