The gerund form of the verb mat- “eat” appearing the (1948) 3rd. sg. possessive form matietta “his eating” (PE22/119); in later Quenya this would be matierya.

A noun in The Etymologies of the 1930s glossed “matrimony” derived from the root ᴹ√BES “wed” (Ety/BES). The same word ᴱQ. vesta appeared in the Qenya Lexicon of the 1910s with the gloss “state of marriage”, but there it was based on the early root ᴱ√VEŘE [VEÐE] (QL/101). It was also mentioned as a cognate of ᴱN. gwedhw “matrimony” in Early Noldorin Word-lists of the 1920s, but there it was a derivative of ᴱ√wed- (PE13/146).

A noun glossed “food, meal” in the Declension of Nouns from the early 1930s with a stem form matt- (PE21/27), clearly based on ᴹ√MAT “eat”. Tolkien specified that as the suffix -mat, it was the basis of names for meals (PE21/32). The Qenya Lexicon of the 1910 also had ᴱQ. mat (matt-) “meal, meal time” under the early root ᴱ√MATA “eat” (QL/59).
Neo-Quenya: For purposes of Neo-Quenya I would use this word only for “meal”, and would instead use Q. matta for “food”.
