úmë (1) vb. pa.t. of um- (and u-?), q.v. (UGU/UMU)
úmë (2) "great collection or crowd of things of same sort" (a struck-out note gave the rejected gloss "largeness") (VT48:32), “throng, great concourse of things without order” (PE17:115). Compare úvë.
-úmë (3) suffix "large" (of quantity)", as in liyúmë "host" (VT48:32)
Úmaiarpl. noun, Maiar (see Maia) who became evil and followed Melkor, like the Balrogs (MR:79). Sg. #Úmaia.
un- intensive prefix used before qu; the assimilated variant um- is said to occur before p, and "b" (the latter evidently = vdeveloped from prehistoric b, but following um- its original quality would be preserved so that we would see umb-). This prefix is reportedly only used "in evil sense"; otherwise the intensive prefix is an- (and assimilated variants thereof). (VT45:5)
únaadj. "deprived of, destitute, forlorn" (VT39:14). The plural form *únë is not to be confused with the pa.t. of the negative verb ua, q.v. – An unglossed word úna, cited in VT49:28, rather seems to be a negated form of ná “is”.
únatnoun "a thing impossible to be or to be done" (VT39:26) Cf. ú- and nat.
