ᴹQ. qelet (qelett-) n. “corpse” (Category: Corpse, Body)
A noun for “corpse” in The Etymologies written around 1937 derived from primitive ᴹ✶kwelett- under the root ᴹ√KWEL “fade (away)” (Ety/KWEL). It had a plural form qeletsi indicating a stem form of qelets-, but that is inconsistent with its attested primitive form; its plural may instead be a conceptual remnant of the Early Qenya sound change whereby [ti] became [tsi] (PE12/23).
Conceptual Development: ᴱQ. qelet “corpse” appeared in the Qenya Lexicon of the 1910s under the early root ᴱ√QELE “perish, die, decay, fade”, but there its stem form was qelekt- (QL/76). ᴹQ. qelet “corpse” reappeared in the Declension of Nouns from the early 1930s, but there its stem form seems to be qelet- (PE21/33, 35). Its early 1930s nominative plural qeletsin also shows ti > tsi (PE21/35).
Neo-Quenya: For purposes of Neo-Quenya, I’d assume a stem form quelett- (and plural queletti) consistent with its primitive form. If the stem form was quelets-, then the uninflected form would be **queles, since final -ts became -s (PE19/104).
