A noun for “finger” in the Qenya Lexicon of the 1910s under the early root ᴱ√TENE “touch, feel” (QL/91). It was also mentioned in the contemporaneous Poetic and Mythological Words of Eldarissa, but with -nd- written above it indicating a variant form tenda (PME/91). A similar word tenge “finger” appeared Early Qenya Word-lists of the 1920s (PE16/137), but ᴱQ. lepta was written next to it, perhaps as a replacement, since after this point finger-words were primarily based on √LEP.

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.
