ᴺS. [G.] ^salcha- v. “to scythe or mow” (Category: to Mow, Reap)
A verb appearing as G. salca- “to scythe or mow” in the Qenya Lexicon of the 1910s (GL/66), clearly a cognate to ᴱQ. silki- “mow, scythe, mow down” in the contemporaneous Qenya Lexicon under the early root ᴱ√SḶKḶ¹ also having to do with “grass” words (QL/84).
Conceptual Development: The Etymologies of the 1930s updated the basis for “grass” words to ᴹ√SALAK+wē (Ety/SALÁK), so I think this Gnomish verb can be salvaged for purposes of Neo-Sindarin. However, in Sindarin phonology it would become ᴺS. salcha- “to scythe or mow”.
