Ilk. (n)gôl adj. “wise, magical”
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 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 initial [ŋg] became [g] in Ilkorin.
See Ilk. initial nasals usually vanished before stops for further discussion.
