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 in the Qenya Lexicon of the 1910s marked as archaic [†] and glossed “broad, vast”, derived from primitive ᴱ√EI̯KA (QL/29). This Qenya word was also mentioned in the contemporaneous Gnomish Lexicon (GL/32) and Gnomish Lexicon Slips modifying that document (PE13/113), in both cases as a cognate to G. eg whose principle meaning was “far”. This Gnomish cognate was also mentioned in the Qenya Lexicon, but without translation.
