Uin (2) masc. name, "the primeval whale" (LT1:263)
Uinen (Uinend-, as in dative Uinenden) fem. name, used of a Maia, spouse of Ossë (UY, NEN). Adopted and adapted from Valarin (WJ:404), though it is also said that it contains -nen "water" (SA:nen); the latter explanation may be folk etymology. In the Etymologies, the name is derived from the same stem (UY) as uilë "long trailing plant, especially seaweed".
uitointerjection “it is not that” (emphatic word for “no”?) Compare ui, náto (VT49:28, 29)
úχarinadj. “unmarred” (PE17:150), this would be úharin in more standard spelling (and later pronunciation). In a more widely published source, the word for “unmarred” is alahasta, q.v.
Ulban (Ulband-) noun "monster" (a name of Melko) (LT1:260)
ulcaadj. "evil, bad, wicked, wrong" (QL:97, VT43:23-24, VT48:32, VT49:14; compounded in henulca "evileyed", SD:68); variant olca, q.v. Compare noun ulco. The adj. ulca may also itself be used as a noun “evil”, as in the ablative form ulcallo “from evil” (VT43:8, 10) and the sentence cé mo quetë ulca *”if one speaks evil” (VT49:19).
