A noun appearing as ᴱQ. silkesse “harvest” in the Qenya Lexicon of the 1910s under the early root ᴱ√SḶKḶ¹ that was also the basis for “grass” words (QL/84).

Conceptual Development: The Etymologies of the 1930s updated this root to ᴹ√SALAK+wē for “grass” words (Ety/SALÁK), so I think this Early Qenya word can be updated to ᴺQ. salcessë “harvest”. I would assume this word refers to the product of a harvest = “*produce”, as opposed to yávië which is the time or act of harvesting.
