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.

ara

root. (be) dry

A root in the Qenya Lexicon of the 1910s meaning “(be) dry” (QL/32). Given the many uses to which √AR was put later, it is unlikely this sense remained valid in Tolkien’s later writing; the later root ᴹ√PARAK and its derivatives is probably better for the purposes of Neo-Eldarin writing.

sah(y)a

root. be hot

A root given as ᴱ√SAHA or ᴱ√SAHYA and glossed “be hot” in the Qenya Lexicon of the 1910s, with derivatives like ᴱQ. sá “fire” and ᴱQ. Sahóra “the South” (QL/81). It also had derivatives in the contemporaneous Gnomish Lexicon such as G. sâ “fire” and G. sair “hot” (GL/66). There are no signs of this root in Tolkien’s later writing.
