A root glossed “emerge (especially from water, opp[osite] of dive)” appearing in the Quenya Verbal System written in 1948, replacing rejected roots ᴹ√KUSU and ᴹ√KHUSU of similar meaning (PE22/127). The page where it appeared was crossed out, but I think it’s worth retaining this root for the purposes for Neo-Eldarin, since there are no better alternatives for “emerge” attested in Tolkien’s published writings.
