[Middle English, from an apron, alteration of a napron, from Old French naperon, diminutive of nape, tablecloth, from Latin mappa, napkin; see map.]

from Wiktionary, Creative Commons Attribution/Share-Alike License

Earlier napron, from Old French napperon, diminutive of nappe ("tablecloth"), from Latin nappa ("napkin"). The phrase a napron was reinterpreted as an apron, that is why the initial n is now missing.
