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.
