Early Quenya
qolimo
noun. invalid
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.
Quenya
quolimo
noun. invalid
A noun appearing as ᴱQ. qolimo “invalid”, apparently an agental form of ᴱQ. qolo- “to ail”, hence = “✱one who ails” (QL/78).
Neo-Quenya: I’d retain ᴺQ. quolimo “invalid” for purposes of Neo-Quenya. Not all Neo-Quenya writers accept quo- as a valid combination; see the entry on how [[q|[wo] became [o]]] for further discussion.
