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.

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.
