ava- (4) vb with pa.t.avanë. This verb is not clearly glossed; apparently meaning refuse or prohibit (WJ:370). Cf. áva, Avamanyar. What is seems to be more or less the same verb has its principal tenses listed (with the ending -n “I”) in VT49:13: aorist avan, present ávan (ávëan), future auvan for older avuvan, past avanen or auvan, perfect avávien. In one version of the paradigm, the present tense ávëan and past avanen are marked as archaic/poetic forms. One text seemingly uses the pa.t. aunë in the sense “was not”, as a negative verb, but this may have been a short-lived idea of Tolkien’s (the text was revised).
Avacúma place-name, "Exterior Void beyond the World" (AWA, (OY) )
avahairaadj. "remote, far" (KHAYA)
Avallónë place-name; haven and city on Tol Eressëa. In the Akallabêth the city is said to be so named because it is "of all cities the nearest to Valinor", but the etymology is not further explained. The Etymologies gives Avalóna "the outer isle" = Tol Eressëa (LONO, (AWA), VT45:28)
