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.

Early Primitive Elvish

kana

root. *lead (metal)

A root in the Qenya Lexicon of the 1910s whose derivatives all began with kanu- and had to do with metallic lead (QL/44). The root √KAN had various other meanings in Tolkien’s later writing, but I think it is possible to theorize the existence of a Neo-Eldarin root ᴺ√KANU “lead (metal)” in order to retain these early words.

gana Speculative

root. young

A hypothetical early root that would explain words appearing in the Gnomish Lexicon of the 1910s such as ᴱQ. kana and G. gân “young” (GL/37). There are no signs of this root in Tolkien’s later writings.
