A Doriathrin name for the Silmarils, a combination of the genitive form of (n)gold “Noldo” and mîr “jewel” (Ety/MIR, ÑGOLOD), hence: “✱Noldo-jewel”. It also appeared in the variant form Goldomir, which may hint at the primitive form of the genitive.

A Doriathrin noun for “magic, lore” from the primitive root ᴹ√ÑGOL (Ety/ÑGOL), most likely from the primitive form ✱✶ŋgolwe based on its Quenya cognate ᴹQ. nolwe. In the entry for ÑGOL in The Etymologies, it appeared as (n)golo, indicating a variation of the usual rule that [[ilk|initial [ŋg] became [g]]] in Ilkorin. After its final vowel was lost, the [[ilk|final [w] became [u]]], which then became [o], the only Doriathrin example of this second change.
