Urundil

copper-lover

Urundil masc. name, "copper-lover" (PM:365); this may suggest #urun as one word for "copper", unless this is the ending -ndil "friend, lover" suffixed to #uru- as a reduced form of urus, q.v.

urundil

masculine name. Copper-lover

An early sobriquet of the father of Nerdanel, more widely known than his given name Sarmo (PM/366). This name is a compound of the root √URUN “copper” and the suffix -(n)dil “-friend, -lover”. In later writings, Tolkien changed his given name from Sarmo to Mahtan, so perhaps this sobriquet no longer applied.
