From Proto-Hellenic *erutʰrós, from Proto-Indo-European *h₁rudʰrós (“red”), from the root *h₁rewdʰ-.
Compare Mycenaean Greek 𐀁𐀬𐀲𐀨 (e-ru-ta-ra). Cognates include Russian рёдрый (rjódryj), Sanskrit रुधिर (rudhirá), Latin ruber, Tocharian A rtär, Tocharian B ratre, and Proto-Germanic *raudaz (English red). Note that Greek is the only branch to preserve the sound of the laryngeal *h₁ at the beginning of the word, which became ε (e).
