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.
(n)gôl
adjective. wise, magical
gôl
noun. light
A (rejected?) Doriathrin noun for “light” derived from primitive ᴹ✶gālæ appearing in The Etymologies (Ety/KAL, EtyAC/KAL). According to Christopher Tolkien’s notes, it was part of a rejected etymology for the name Thingol, but it isn’t clear whether this noun was rejected or if it was just the etymology. Its long primitive vowel [[ilk|[ā] became [ō]]] as was the norm in Ilkorin.
gôl
adjective. wise, magical
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 adjective for “wise, magical” derived from the root ᴹ√ÑGOL (Ety/ÑGOL, THIN). In an earlier version of this entry, the forms were ngûl and gûl, but these were rejected (EtyAC/ÑGOL). It may be that Tolkien was considering making this another case where [[ilk|long [ō] became [ū]]] in Ilkorin, but he rejected the idea. In the entry for ÑGOL in The Etymologies, it appeared as both ngôl and gôl; the first of seems to be a variant of the usual rule that [[ilk|initial [ŋg] became [g]]] in Ilkorin.
