The word ᴱQ. nyēni “she-goat” appeared in the Qenya Lexicon of the 1910s as a feminized form of ᴱQ. nyé “bleat” (QL/68). It also appeared in the Poetic and Mythological Words of Eldarissa (PME/68).

Neo-Quenya: I’d retain ᴺQ. nyéni for “(she) goat” for purposes of Neo-Quenya; see ᴺQ. nyé “bleat” for the rationale, and ᴺQ. naico “goat” for possible alternatives.
