Etymology: The adjective "aero" is a back-formation, meaning it was created by stripping a supposed suffix from an existing word, and the word it came from is the prefix "aero-". That prefix comes from Ancient Greek "aḗr" (ἀήρ), whose genitive form "aéros" (ἀέρος) gave English its combining element for air, as in "aeronautics" and "aerosol." Because English speakers met the prefix so often in compounds, they treated the first part of words like "aeronautical" as a standalone word in its own right. The point of the story is that a shortened form was pulled out of longer words rather than built from the Greek root directly. This is a common pattern: a speaker or writer sees a recurring element, decides it works alone, and starts using it that way. The result is a word that sounds like a plain adjective, yet its existence depends on the much older Greek word for air.
