The word ᴱQ. nyé “bleat, cry of goat or sheep” appeared in the Qenya Lexicon of the 1910s as a derivative of the early root ᴱ√NYE(NE) “bleat” (QL/68). This root was connected to ᴱ√NYEHE “weep” which was the basis for words like ᴱQ. nie “tear”.

Neo-Quenya: The word ᴹQ. nie “tear” reappeared in Tolkien’s later writings as a derivative of ᴹ√NEY, and I think ᴺQ. nyé “bleat” might be retained in Neo-Quenya as an onomatopoeic form, possibly related to this root.
