About This Root
From Old French air (air, atmosphere), via Latin aer, ultimately from Greek aēr. As a standalone English word and root, it generates a large family of compounds — airplane, airline, airspace, airborne, airmail. Most are transparent in meaning. This Germanic-influenced form runs parallel to the more learned Greek root aer-/aero-.
