A noun appearing as ᴱQ. ore (ori-) “seed, grain” in the Qenya Lexicon of the 1910s under the early root ᴱ√ORO² (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 be used both collectively for a mass of “grain” as well as an individual “grain”.
