There are more words but they are from Tolkien's earlier conceptional periods. Tolkien likely changed these words as he evolved the aesthetics and completeness of the languages. You may even find languages that Tolkien later rejected. Do not mix words from different time periods unless you are familiar with the phonetic developments.
Below: Tolkien's Late Period (1950–1973). These are from Tolkien's late conceptual period — his most settled forms of the languages. Prefer these over the earlier ones above when composing new text.
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.
