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 rejected root in The Etymologies of the 1930s glossed “precede, come forward, hence” providing an etymology for the words for Elf (Ety/EDE). The rejected Noldorin form N. Edhel may have been an early attempt to revise N. Eledh “Elf”, which in Sindarin became S. Edhel < √DEL (WJ/363-4). As such, this root may have been an early iteration of √DEL “walk, go, proceed, travel”.
