Gnomish

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 became -ol, as in tachol < ✶tankl(a) (PE18/100).
