From Etruscan *𐌄𐌋𐌄𐌉𐌅𐌀 (*eleiva) (whence 𐌄𐌋𐌄𐌉𐌅𐌀𐌍𐌀 (eleivana, “of oil”)), itself from Pre-Classical Ancient Greek *ἐλαίϝα (*elaíwa) (compare Mycenaean Greek 𐀁𐀨𐀷 (e-ra-wa), Ancient Greek ἐλαία (elaía)), or perhaps from the same source. In any case, most likely from a Mediterranean Pre-Greek source, possibly Proto-Berber *wlw (“wild olive”). More questionably, possibly from Proto-Indo-European *h₁loywom (compare Old Church Slavonic лои (loi, “tallow”), Old Armenian եւղ (ewł, “oil”)).
