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.
A noun in the Gnomish Lexicon of the 1910s appearing as {ald >>} âl “wood (material)” (GL/19), a derivative of the root ᴱ√ALA “spread” which was the basis of other “wood” words, as suggested by Christopher Tolkien (LT1A/Aldaron). This word appeared unglossed in Gnomish Lexicon Slips as a derivative of ᴱ✶alda, but was equated to G. awl, possibly “lofty” (PE13/109).
