óros

Either from ὄρνυμι (órnumi, “I raise”), or possibly directly from a Proto-Indo-European *h₃eros.

Compare Sanskrit ऋष्व (ṛṣvá). Possibly related are the personal names Ὀρειάς (Oreiás), Mycenaean Greek 𐀃𐀩𐁀 (o-re-ha, “Oreās”), and Ὀρέστης (Oréstēs), Mycenaean Greek 𐀃𐀩𐀲 (o-re-ta, “Orestās”).

The sense "desert" is a semantic loan from Demotic tw (“mountain, desert”), from Egyptian ḏw (“mountain”).
