ᴱ√MURU root. “slumber”
A root in the Qenya Lexicon of the 1910s glossed “slumber”, with derivatives like ᴱQ. murme “slumber, sleep” and ᴱQ. muru- “to slumber” (QL/63). In the contemporaneous Gnomish Lexicon it had derivatives like G. maur “a dream, vision” and G. murtha- “dream” (GL/57-58). In Tolkien’s later writing sleep and dream words were mostly derived from √LOR.
