Etymology: "Aeromarine" is a plain compound: "aero-", from Greek "aēr" meaning air, joined to "marine", from Latin "marinus" meaning of the sea, itself from "mare" meaning sea. Put together, the pieces describe something that belongs to both air and sea at once, which is exactly the meaning given for the adjective and noun. The prefix "aero-" is the productive one here. It has long been used to form words about flight and the atmosphere, such as "aeronautics" and "aerodynamics", so "aeromarine" follows that pattern by pairing it with a maritime root. The word's use is therefore a matter of combining familiar building blocks rather than a story of any single coinage.
