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. maloglin or maloglin “daffodil, [lit.] yellow song” in the Gnomish Lexicon of the 1910s (GL/56). Its initial element is clearly G. malon “yellow”, and its second element is probably derived from the early root ᴱ√LIŘI [LIÐI] “sing” (QL/54).
Neo-Sindarin: For purposes of Neo-Sindarin, I would update this word’s elements to [N.] malen “yellow” (< ✱malina) and lind “song”. If we assume it is the result of an ancient compound, the i in ✱malina would not undergo *a*-affection because the element was non-final. As a result, the surviving i would induce *i*-affection on the *a* in the first syllable, changing it to *e* so that end result would be ᴺS. melillin “daffodil, (orig.) yellow song”: ✱malina-linde > ✱melin(a)-lind(e) > melillin.
