bothli

noun. oven

A noun appearing as G. bothli “oven” in the Gnomish Lexicon of the 1910s, derived from primitive ᴱ✶mᵇāsḷ (GL/23) and thus based on the early root ᴱ√M(B)ASA “cook, bake” (QL/63).

Neo-Sindarin: Since √MBAS “bake” continued to appear in Tolkien’s later writings, I would retain this word but adapt it as ᴺS. bothol “oven” to better fit later Sindarin phonology: [mbāslǝ] > [mbǭsḷ] > [mbauθḷ] > [boθol]. Here final syllabic ḷ became -ol, as in tachol < ✶tankl(a) (PE18/100).

torma

noun. oven

A word in the Qenya Lexicon of the 1910s glossed “oven” under the early root ᴱ√TORO whose derivatives had to do with baking (QL/94). The word also appeared in the Poetic and Mythological Words of Eldarissa (PME/94).

urna

noun. oven

A noun appearing as ᴱQ. urna “oven” in the Qenya Lexicon of the 1910s under the early root ᴱ√USU or ᴱ√UŘU [UÐU] whose derivatives had to do with burning (QL/98).

Neo-Quenya: I would retain ᴺQ. urna for purposes of Neo-Quenya, reconceived of as a derivative of the later root √UR “heat”.
