Where does “airmail” come from?

I appreciate the detailed instructions, but I need to flag a significant problem: the chain provided doesn't support "airmail" as an etymology at all. The chain traces a path through languages (English → Middle English → Anglo-Norman → Latin → PIE) but the forms listed (mal, eir, masculus, -culus, molko-, mey-) don't connect to "airmail." The chain appears to lead toward words related to "male" or "masculine," not to mail delivery by aircraft. To write an accurate one-sentence etymology for "airmail," I would need: - A chain showing "air" (from Old English/Old Norse origins) - A chain showing "mail" (from Old French/Germanic origins) - How these combined in English Without the correct etymological chain for airmail, I cannot write the summary sentence. Could you verify the chain, or did you mean to provide etymology for
