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!
The word ᴱQ. rent (renty-) “spittle, saliva” appeared in the Qenya Lexicon of the 1910s under the early root ᴱ√RET͡YE (QL/79). In Early Noldorin Word-lists of the 1920s Tolkien had ᴱQ. rekka as a cognate of ᴱN. crech “spittle” from primitive ᴱ✶kǝ̀rekka (PE13/140).
Neo-Quenya: I’d retain ᴺQ. recca “spittle, ✱saliva” for purposes of Neo-Quenya.
