A word appearing as ᴱQ. sarma “a saw” in the Qenya Lexicon of the 1910s, a noun form of ᴱQ. sara- “saw” under the root ᴱ√SARA of the similar meaning (QL/82).
Neo-Quenya: Since I retain ᴺQ. sara- “to saw [wood]” for purposes of Neo-Quenya, I would retain the noun ᴺQ. sarma “saw” as well.
A verb appearing as ᴱQ. sara- “saw” in the Qenya Lexicon of the 1910s derived from the early root {ᴱ√SAŘA >>} ᴱ√SARA, apparently of the same meaning (QL/82). Its Gnomish cognate G. thar- “saw (up)” indicates an actual root form of ✱ᴱ√ÞARA.
Neo-Quenya: The root √THAR means “across” in Tolkien’s later writings, but I think ᴺQ. sara- “to saw [wood]” is still salvageable from an original sense of “✱(cut) across”.
