A noun appearing as G. authmadri “midday meal” in the Gnomish Lexicon of the 1910s, a combination of G. auth “noontide” and G. madri “meal” (GL/20).

Neo-Sindarin: I would update this word to ᴺS. nedhwad “lunch, (lit.) middle-meal” for purposes of Neo-Sindarin using my preferred word [G.] mâd for “meal” with the prefix [N.] nedh- “mid”, where ancient dm became dhw; compare S. haðw “seat” < ✶khadmā (PE22/148).
