Dan. laur n. “gold”
A noun for “gold” developed from primitive ᴹ✶laurē, and one of the few words explicitly marked as Ossiriandic (Ety/LÁWAR). In this word the long final vowel was lost. Unlike the rules described in the Comparative Tables, this [au] did not become [ō], so perhaps Tolkien changed his mind on the development of [au] in Ossiriandic.
