ᴱ√QINI root. “*squeak”
An unglossed root in the Qenya Lexicon of the 1910s with derivatives like ᴱQ. qíne “squeaking” and ᴱQ. qíni- “speak high, squeak” (QL/77). I think it worth positing a Neo-Eldarin root ᴺ√KWIN “squeak” to preserve these Early Qenya words, though it conflicts with √KWIN “crest, salient or top edge”.
