au- (1) a verbal prefix "off, *away", as in auciri ("k") "cut off" (so as to get rid of or lose a portion); contrast hóciri (WJ:366, 368). Compare au as a variant of the stem awa "away from" (VT49:24) and the adverb au (see #2 below).

ava-
without
ava- (3) prefix "without" (AR2, AWA). In some cases apparently used as a mere negation prefix: The form avalerya in VT41:6 is seemingly a negated form of the verb lerya- "release, set free"; the verb avalerya- is suggested to have the same meaning as the root KHAP = "bind, make fast, restrain, deprive of liberty". Likewise, the verb avalatya- from the same source seems to mean "to close, shut", this being a negated form of a verb *latya- "open" (q.v.)
