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.

immainen

adverb. *by any means

The correlative ᴹQ. immainen appeared in Demonstrative, Relative, and Correlative Stems (DRC) from 1948 (PE23/111), a combination of ᴹQ. imma “any” and the instrumental suffix ᴹQ. -nen.

Neo-Quenya: Since ᴹQ. imma “any” too closely resembles the later prefix Q. im- “same”, for purposes of Neo-Quenya I would update this to ᴺQ. ainen “by any means” using hypothetical prefix ᴺQ. ai(a)- “any”; see that entry for discussion.

imma

any, any at all (in the world/existence); anything

An adjective for “any” appearing in Demonstrative, Relative, and Correlative Stems (DRC). On the page where this first appeared, this was revised to amma then to umma (PE23/99 note #24-25). Despite these revisions, the rest of the document used imma- throughout in forms like ᴹQ. immane “anybody” and ᴹQ. immanome “any place”. The adjective imma could also be used substantively to mean “anything” (PE23/104).
