Beware, older languages below! The languages below were invented during Tolkien's earlier period and should be used with caution. Remember to never, ever mix words from different languages!

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