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 (plural) pronominal form of ᴹQ. hrim- appearing in Demonstrative, Relative, and Correlative Stems (DRC) from 1948 (PE23/103), as in á anta nin hrimi “give me many, lots [pl.]”. It had a longer form ᴹQ. hrīmani with variants [hrīma]nor and [hrīma]ri, apparently plural masculine and feminine forms.
Neo-Quenya: For purposes of Neo-Quenya I would adapt this to ᴺQ. rimi “(very) many” using rim- “many” to be more compatible with Tolkien’s later writings.
