nuhu

root. bow, bend down, stoop, sink

ū

root. under

The root ᴱ√Ū⁽¹⁾ “under” appeared in the Qenya Lexicon of the 1910s as a reduced form of {ᴱ√UGU >>} ᴱ√UƷU, with derivatives like ᴱQ. ū “beneath” and ᴱQ. umbe “dale, dell” (QL/96-97). It also had derivatives in the contemporaneous Gnomish Lexicon such as G. um⁽⁾ “lowlying” and G. umbel “a dell” (GL/74). Tolkien noted that ᴱ√Ū also meant “not”, and contrasted ᴱ√Ū¹ “under” with ᴱ√NŪ (ᴱ√NUHU) of similar meaning (QL/68, 96). Indeed, in Tolkien’s later writings, √NŪ/UNU was the usual basis for “under” words, and ᴱ√Ū¹ “under” seems to have been abandoned.
