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 ᴱQ. ore (ori-) “seed, grain” in the Qenya Lexicon of the 1910s under the early root ᴱ√ORO (QL/70). Tolkien indicated its primitive form was ✱[or]ı̯ǝ. Tolkien also indicated that its root may be better analyzed as o- + ᴱ√RIẎI “scatter” (QL/70, 80).
Neo-Quenya: There are indications that the root ᴹ√RĪI̯ survived until at least the early 1930s, so I would salvage this early word but update it to ᴺQ. ori “grain” = o + RĪ. I would use the later word ᴹQ. erde for “seed”, however. I would assume that like English “grain”, ori can be used both collectively for a mass of “grain” as well as an individual “grain”.
