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. calon “grown (of plants), budd[ing], in blade (of corn)” in the Gnomish Lexicon of the 1910s, based on the early root ᴱ√cala having to do with growth (GL/25). Initially Tolkien said this word was the equivalent of G. côl “vegetable”, but this was deleted.
Neo-Sindarin: For purposes of Neo-Sindarin, I would update this word to ᴺS. galen “grown (esp. of plants)” based on the later root √GAL “grow”.
