There are more words but they are from Tolkien's earlier conceptional periods. Tolkien likely changed these words as he evolved the aesthetics and completeness of the languages. You may even find languages that Tolkien later rejected. Do not mix words from different time periods unless you are familiar with the phonetic developments.
Below: Tolkien's Late Period (1950–1973). These are from Tolkien's late conceptual period — his most settled forms of the languages. Prefer these over the earlier ones above when composing new text.
An adjective appearing as G. barn or baron “tilled, inhabited” in the Gnomish Lexicon of the 1910s (GL/21), clearly derived from the early root ᴱ√MBARA “dwell, live” (QL/63). As such, likely this word originally meant “inhabited” and the sense was later extended to “inhabited and prepared for cultivation” = “tilled”. As such it likely refers primarily to inhabited land rather than inhabited dwellings, and more specifically to tilled land inhabited by an agricultural people rather than simple hunter-gatherers.
Neo-Sindarin: Since √MBAR continues to appear in Tolkien’s later writings, I would retain ᴺS. baron “tilled, inhabited” for purposes of Neo-Sindarin.
