"high, snow-capped mountain," especially in Switzerland, 1590s, from Alps, from French Alpes, from Latin Alpes "the Alps," perhaps from altus "high," or albus "white" or from a Celtic word (according to Maurus Servius Honoratus the grammarian), or a borrowing from a non-Indo-European language. Alps, the central European mountain range, attested by that name in English from late 14c.
