kemna

adjective. of earth, earthen

An adjective in The Etymologies of the 1930s glossed “of earth, earthen” derived from the root ᴹ√KEM “soil, earth” (Ety/KEM; EtyAC/KEM). In The Etymologies as published in The Lost Road, Christopher Tolkien gave the form as kemina (LR/363), but in “Addenda and Corrigenda to the Etymologies” Hostetter and Wynne clarified that the actual form was kemna (VT45/19).

Conceptual Development: The Qenya Lexicon of the 1910s had ᴱQ. kereksa “of earthenware”, an adjectival form of ᴱQ. keres “earthware” under the early root ᴱ√KERE (QL/46). There was an sk written nearby indicating an alternate (or archaic) form kereska as suggested by the editors.
