Perhaps derived from the Greek verb ἀείρω (aeiro), αἴρω (airo) "to lift up, to raise". In Greek mythology, Aero (also called Haero, Aerope and Maerope) was a princess of the island of Chios, a daughter of Oenopion and Helice. She was beloved by Orion, who was, in consequence, blinded by her father.
From the English combining form (aero-), ultimately from Greek ἀήρ (aer) "air" (originally "the lower air, the air that surrounds the earth" as opposed to αἰθήρ (aither) "the upper air"; compare Aither). In the 1993 video game Aero the Acro-Bat, this is the name of an anthropomorphic bat that performs in a circus.
