ᴺS. [G.] ^noch n. “acorn” (Category: Acorn)
A noun appearing as G. nocha “an acorn” in the Gnomish Lexicon of the 1910s (GL/61). It had no obvious Qenya cognate, so its derivation is unclear.
Neo-Sindarin: Since there are no later words for “acorn”, I would adapt this word as ᴺS. noch “acorn” for purposes of Neo-Sindarin.
