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.
An adjective or adverb in the Qenya Lexicon of the 1910s appearing as tā “†high” or “high above, high up” under the early root ᴱ√TAHA (QL/87). It was mentioned again as tá “above” in the English-Qenya Dictionary of the 1920s, but in that document it was deleted (PE15/67). The Qenya word tá was also given as the equivalent of ᴱN. dá “high” in Early Noldorin Word-lists of the 1920s (PE13/141, 161).
