A word appearing as ᴱQ. tyetse “a teat” in the Qenya Lexicon of the 1920s under the early root ᴱ√TYETE “give suck” (QL/50), also appearing in the contemporaneous Poetic and Mythological Words of Eldarissa with the gloss “teat” (PME/50).

Neo-Quenya: I think this word is worth retaining as ᴺQ. tyetsë “teat, *nipple” for purposes of Neo-Quenya.
