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.
The Qenya Lexicon of the 1910s had ᴱQ. orta “above” under the early root ᴱ√ORO (QL/70). The English-Qenya Dictionary of the 1920s had orta “above” as an adverb, plus atta/orta as prepositions, but these were all deleted.
Neo-Quenya: Luinyelle and Arael coined a neologism ᴺQ. orsa [þ] “upper, above” as an adjective, posted to the Vinyë Lambengolmor Discord Server (VLDS) on 2022-05-23 and inspired by G. ortha and ᴺS. orth “upper”. As pointed out by Parmandil in 2024, this cannot be derived from ✱ortha since otherwise rth > rt, so it must be from or(o)thā; compare ursa [þ] “rage” < ✱ur(u)tha.
