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 verb in The Etymologies of the 1930s for “kindle” derived from the root ᴹ√NARTA of the same meaning (EtyAC/NARTA). This root is probably just a causative verb formation from ᴹ√NAR “flame, fire”, more literally “✱make fire”. Hence I think this verb can be used in the general sense of “✱ignite, inflame, set fire to”, etc.
