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 appearing as G. limp and longer limpelis in the Gnomish Lexicon of the 1910s with the gloss “the drink of the fairies” (GL/54). Tolkien tentatively revised these in pencil to limfa and limfelis, and these two forms appeared in a name list from this same period (PE15/7). These forms did not appear again, but its Quenya cognate ᴹQ. limpe “wine” appeared in The Etymologies of the 1930s (Ety/LIP).
