ᴹ√MBAW root. “compel, force, subject, oppress”
A root in The Etymologies of the 1930s glossed “compel, force, subject, oppress”, with derivatives ᴹQ. maure/N. baur “need” and N. baugla- “to oppress” (Ety/MBAW), the latter serving as the basic for one of the names of Morgoth: N. Bauglir “Constrainer” (LR/206). Tolkien’s continued use of S. Bauglir in later writings (S/104) indicate the ongoing validity of this root.
