Elements
Word Gloss pint “tail” lint “fluff, down, soft stuff”
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 word appearing as ᴱQ. pimpilin (pimpilind-) “hanging tail, tassel” in the Qenya Lexicon of the 1910s, an elaboration of ᴱQ. pint (pimp-) “tail” (QL/74). The meaning of the second element is unclear: its form resembles ᴱQ. lin(d-) “musical voice, tune” (QL/54) but that meaning doesn’t fit. The second element might instead be a variant of ᴱQ. lint (linty-) “fluff, down, soft stuff” (QL/54).
Neo-Quenya: Since I retain ᴺQ. pimpë for “tail”, I’d retain ᴺQ. pimpilin for “tassel, hanging tail” without being overly concerned about the meaning of its second element.
