Aulëonnar (sg. #Aulëonna) noun "Children of Aulë", a name of the Dwarves (PM:391). See onna.
aurënoun "sunlight, day" (SA:ur), “day (of light), a day of special meaning or festival” (VT49:45). locative auressë "in (the) morning" in Markirya, allative aurenna *”on the day” (VT49:43-45). Also compare amaurëa.
Aurel (Aureld-, e.g. pl. Aureldi) noun "Elf who departed from Beleriand to Aman" (while the Sindar stayed there) (WJ:363). Also Oarel, q.v. Earlier Auzel.
ausa (þ) noun "a dim shape, spectral or vague apparition" (VT42:10, cf. 9). Compare fairë.
ausiënoun "wealth" (LT2:336; rather lar or alma in Tolkien’s later Quenya)
auta- (1) vb. "go away, leave" (leave the point of the speaker's thought); old "strong" past tense anwë, usually replaced by vánë, perfect avánië – but when the meaning is purely physical "went away (to another place)" rather than "disappear", the past tense oantë, perfect oantië was used. Past participle vanwa "gone, lost, no longer to be had, vanished, departed, dead, past and over" (WJ:366)
auta- (2) vb. "invent, originate, devise" (GAWA/GOWO) This could be obsoleted by # 1 above; on the other hand, the verbs would be quite distinct in the past tense, where auta- #2 would likely have the straightforward form *autanë.
autënoun "prosperity, wealth", also adj. "rich" (LT2:336; rather alma, and as adj. alya or lárëa, in Tolkien’s later Quenya)
