Beware, older languages below! The languages below were invented during Tolkien's earlier period and should be used with caution. Remember to never, ever mix words from different languages!
A noun(?) in the Qenya Lexicon of the 1910s glossed “release” as combination of ᴱQ. ere- “out” and ᴱQ. fainu- “to release” (QL/36). Tolkien said that “f [was] retained because of cpd. sense”, in other words intervocalic f did not become v as it usually did in Early Qenya (PE12/20) because it was part of a recognized compound. This word also had a variant erevainu where the intervocalic change did occur.
