Beware, older languages below! The languages below were invented during Tolkien's earlier period and should be used with caution. Remember to never, ever mix words from different languages!

Early Quenya

-(n)dóre

suffix. -illion, *large number suffix

The suffix ᴱQ. -(n)dóre appeared in various “-illion” words in the typescript version of the Early Qenya Grammar (EQG) of the 1920s: million, billion, trillion, and so forth (PE14/83). In the manuscript version of EQG, the suffix was ᴱQ. -(n)dóra and meant only “million”, as in one million, two million, three million (PE14/50).

Neo-Quenya: For purposes of Neo-Quenya, I would keep ᴺQ. -(n)dórë as the basis for Quenya “-illion” words.
