etingul

proper name. one of Noldorin race who remained in Kor

A term for the Noldor who remained in Valinor appearing only in linguistic notes from the 1930s (PE21/33), its initial element is derived from primitive ete “back, below”.

lóna

adjective. dark

nyarro

noun. rat

A noun in The Etymologies of the 1930s glossed “rat” derived from primitive ᴹ✶nyadrō under the root ᴹ√NYAD “gnaw” (Ety/NYAD). In The Etymologies as published in The Lost Road, the form was incorrectly given as nyano (LR/379), but Carl Hostetter and Patrick Wynne corrected this to nyarro in their Addenda and Corrigenda to the Etymologies (VT46/7).

qesset

noun. pillow

A noun for “pillow” in The Etymologies of the 1930s under the root ᴹ√KWES having to do with feathers (Ety/KWES). Given its cognate N. pesseg, its stem form is probably quessec- as suggested by Helge Fauskanger (QQ/quesset).

seler

noun. sister

A noun for “sister” in The Etymologies of the 1930s derived from the root ᴹ√THEL or THELES of the same meaning, with an irregular plural selli (Ety/THEL), where the stem form sell- is because the Quenya syncope caused the second e to be lost and then the ancient ls became ll.

Neo-Quenya: In notes from the late 1960s, Tolkien introduced a new word nésa for “sister” (VT47/14). However, I think seler might be retained to mean a “metaphorical” sister, a close female associate who may or may not be related by blood, as with such words as meletheldi “love-sister, ✱close female friend” or ᴹQ. oselle “sworn sister”. In this sense, nésa would be limited to biological relationships, but seler would refer to sisterly (or sister-like) affection.
