Uncertain. Traditionally derived from either of the Proto-Indo-European roots *(h₃)rew-d- (“to tear up, dig up”) or *gʰrew-d- (“gravel, stone”), along with rūdus (“debris, rubble”) and rudis (“rough, raw”); modern scholars however tend to deem this phonetically impossible. Rather, to be considered a substrate word and compared with Proto-West Germanic *arut (“ore”), along with perhaps Sumerian 𒍏 (urud, “copper”); this latter theory is supported by Kroonen. De Vaan, on the other hand, considers this a derivative of Proto-Indo-European *h₁rewdʰ- (“red”), albeit loaned from a likely-extinct Indo-European branch.
