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.

Gnomish

thar-

verb. to saw (up)

A verb appearing as G. thar- “saw (up)” in the Gnomish Lexicon of the 1910s (GL/72), likely based on the early ᴱ√SARA “saw” (QL/82). The Gnomish word indicates an actual root form of ✱ᴱ√ÞARA.

Neo-Sindarin: The root √THAR means “across” in Tolkien’s later writings, but I think ᴺS. thar- “to saw (up)” is still salvageable from an original sense of “✱(cut) across”.
