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 {qanta >>} qanna in Demonstrative, Relative, and Correlative Stems (DRC) from 1948 derived from primitive ᴹ✶kwatnā and translated as “entire, complete, whole” or “entire, altogether” (PE23/101, 106). Unlike ilqa, it could be used with or without an article: i qanna masta “the whole loaf” vs. qanna masta “a whole loaf”. It can also be used undeclined as a modifier to emphasize ilqa, such as: ilqa nóre qanna “the whole land [al]together/entire” = “✱all the whole land”.
Neo-Quenya: In Tolkien’s later orthography, this word would be written quanna.
Conceptual Development: The Early Qenya Grammar (EQG) of the 1920s had ᴱQ. kaina and ᴱQ. kaino “whole”, adjective and noun respectively, both based on ᴱQ. kai “ten” = “all fingers”.
