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.

sóra

cardinal. million; (vaguely) a very great number

A suffix for “long” in the Qenya Lexicon of the 1910s with variants lēni or lēnu, both base on the early root ᴱ√LENE “long” (QL/53). These Qenya suffixes were also mentioned in the contemporaneous Gnomish Lexicon (GL/39).

Early Quenya [PE14/050] Group: Eldamo. Published by

mindóre

cardinal. million

The manuscript version of the Early Qenya Grammar (EQG) of the 1920s had ᴱQ. mindóra “[one] million” (PE14/50), but in the typescript version this became ᴱQ. mindóre “million” (PE14/83), a combination of ᴱQ. min “one” and the “-illion” suffix ᴱQ. -(n)dóre.

Neo-Quenya: I would retain ᴺQ. mindórë “million” for purposes of Neo-Quenya, as we have no better alternatives.
