nólë (ñ) noun "long study (of any subject), lore, knowledge" (SA:gûl, also WJ:383 and MR:350, there spelt ñóle_, the earlier pronunciation. In the Etymologies, stem ÑGOL, the gloss is "wisdom".)_ Compare Nólion. At one point, Tolkien was dissatisfied with ÑGOL as the stem for "wisdom" and introduced the form núlë (q.v.) of slightly dissimilar meaning (PE17:125).
