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 word appearing as ᴱQ. nier (nies-) “honey bee” in the Qenya Lexicon of the 1910s, derived from primitive ᴱ✶neχier under the early root ᴱ√NEHE that was the basis for “honey” and “bee” words (QL/65). It had a variant form nies (niess-). It appeared as nier “bee” in the contemporaneous Poetic and Mythological Words of Eldarissa (PME/65), but in the Gnomish Lexicon it had the forms nier and nion derived from primitive ᴱ✶negeher and ᴱ✶negōn respectively.
Neo-Quenya: In Tolkien’s later writings, the root √NEG “ooze, drip” was still connected to “honey” (PE19/91). Thus I think this word might be salvaged as ᴺQ. nier “bee” derived from an ancient agental formation neger(ŏ), where ege > eʒe > ëe > ie (PE19/63).
