A noun in The Etymologies of the 1930s glossed “gloom, shadow” derived from the root ᴹ√LUM (Ety/LUM). It was an element in the name ᴹQ. Hísilumbe for N./S. Hithlum, more typically given as Q. Hísilómë. However, both the root √LUM “shadow” and derived Quenya words like Q. lumbulë “heavy shadow” continued to appear in Tolkien’s later writings (PE17/168; RGEO/59), so I suspect lumbe may remain valid as well.
