A word appearing as ᴱQ. keres (kerest-) “earthenware” in the Qenya Lexicon of the 1910s under the early root ᴱ√KERE, with a shorter variant ᴱQ. kere that meant both “earthenware” and “earthen jar” (QL/46).
Neo-Quenya: For purposes of Neo-Quenya, I prefer ᴺQ. cemnassë “earthenware, pottery” as an adaptation of [N.] cevnas “earthenware” (EtyAC/KEM).
