nauglamírproper name. Necklace of the Dwarves
Conceptual Development: In the earliest Lost Tales, this name was G. Nauglafring (LT2/221), a form that was retained in the early Silmarillion drafts (SM/33, SM/134), but was replaced with Ilk. Nauglamír later in the 1930s (SM/313, LR/141). In the Etymologies, this name was designated Doriathrin [Ilkorin], with its initial element being the genitive of Dor. naugol “dwarf” (Ety/NAUK, MIR). This form was not updated in the Silmarillion revisions from the 1950s-60s, but no longer fit the phonology of later Sindarin (the expected form would be Nauglavir). Either it was dialectical or (more likely) Tolkien never got around to revising it.
