[airë (3) noun "eternity" (EY, VT45:13)]
ui-verb. to not be, to not do
u-not do, not be
#u- vb. "not do, not be" (1st pers. aorist uin "I do not, am not"), pa.t. úmë (UGU/UMU). A late (ca. 1968) source gives the forms uin, uin(yë) "I am not", uil(yë) "you are not", uis "it is not", uilmë "we are not", uir "are not" and endingless ui *"is not" (VT49:29, 36); these forms were however struck out. The example uin carë "I dont" (PE17:68) combines this negative verb with a following verb in the "simplest aorist infinitive". Compare ua in another late source. See also ui, which (despite its use as an interjection "no") seems to be the endingless 3rd person aorist.
úr(in)proper name. Sun
A late remnant of earlier names for the Sun: ᴱQ. Ûr and ᴹQ. Úrin. In Silmarillion revisions from the 1950s-60s, this name was changed from Úrin >> Naira >> Vása (MR/198), but the form Úr(in) occasionally appeared in some later writings (PE17/148, MR/377). This name was a derivative of the root √UR “heat, be hot” (PE17/148).
Conceptual Development: In the earliest Lost Tales, this name was ᴱQ. Ûr, Ur or Úri “Sun”, but literally meaning “Fire” (LT1/187, QL/98). The name became ᴹQ. Úrin in Silmarillion drafts from the 1930s (LR/240). It was rejected in The Etymologies along with the root form ᴹ√UR, but reappeared sometimes in later writing as noted above.
ua-verb. to not be, to not do
ua-not do, not be
ua- negative verb "not do, not be". If a verb is to be negated, ua (coming before the verb) receives any pronominal endings (and presumably also any endings for plurality or duality, -r or -t), whereas the uninflected tense-stem of the verb follows: With the ending -n for "I", one can thus have constructions like uan carë "I do not" (aorist), uan carnë "I did not" (past), uan cára "I am not doing" (present), uan caruva "I shall not do" (future). The verb ua- can itself be fully conjugated: #ua aorist (or present?), únë (past), úva "(future), #uië (perfect) (the aorist and perfect are attested only with the ending -n "I"). In "archaic Quenya" these tense-forms could be combined with an uninflected aorist stem, e.g. future *úvan carë = later Quenya uan caruva, "I shall not do". In later Quenya, only the forms ua (present or aorist) and "occasionally" the past tense form #únë were used in normal prose (únen* "I did not, was not"). (PE17:144; compare FS for úva** as a future-tense negative verb "will not")
