mat- (1) vb. "eat" (MAT, VT45:32), also given as mata- (VT39:5), pa.t. mantë "ate" (VT39:7). The form matumnë is said to be future-past: "was going to eat", with the "OQ" (Old Quenya?) future-past element umnë (VT48:32; possibly this could function independently as a form of the verb "to be", hence "was to be"). It is not clear if the form matumnë is itself "Old Quenya" as if this is an archaic future-past formation, or it is just umnë (as an independent word) that is archaic. (Note: Tolkien's translation of matumnë is actually "I was going to eat", but the pronoun "I" does not seem to be expressed in the Quenya form.) Adj. or pseudo-participle #matya "eating" in melumatya "honey-eating" (PE17:68)

mat
meal, meal time
mat (matt-) noun "meal, meal time" (QL:59)
-ima
suffix. -able, -ible, adjective suffix, apt to do
-ima adjectival suffix. Sometimes it is used to derive simple adjectives, like vanima "fair" or calima "bright"; it can also take on the meaning "-able" (PE17:68), as in mátima "edible" (mat- "eat"), nótima "countable" (not- "count") and (with a negative prefix) úquétima "unspeakable" (from quet- "speak"). Note that the stem-vowel is normally lengthened in the derivatives where -ima means "-able", though this fails to occur in cenima "visible" (q.v., but contrast hraicénima, q.v.) and also before a consonant cluster as in úfantima "not concealable" (PE17:176). "X-ima" may mean "apt to X" (when the ending is added to an intransitive verbal stem), as in Fírimar "mortals", literally "those apt to die" (WJ:387). The adj. úfantima "not concealable" (PE17:176) also appears as úfantuma (PE17:180), indicating the existence of a variant ending -uma (possibly used to derive adjectives with a "bad" meaning; compare the ending *-unqua next to -inqua, q.v.)
mulë
meal, grist
mulë noun "meal, grist" (PE17:115, 181), replacing polë, q.v.
mulë
noun. meal, meal, *grist, ground grains
polë
meal, grist
[polë (stem poli-) noun "meal, grist" (PE17:115, 181), a word Tolkien decided to replace by mulë; perhaps polë was a variant of porë.]
The verb for “to eat” derived from the root √MAT of the same meaning (VT39/7).
Conceptual Development: This verb and root are quite well established, dating all the way back to ᴱQ. mat- and ᴱ√MATA of the Qenya Lexicon of the 1910s (QL/59) and appearing as ᴹQ. mat- and ᴹ√MAT in The Etymologies of the 1930s (Ety/MAT), as well as numerous other places albeit with occasional variants like mata- (PE12/26). This verb was one Tolkien often used in examples of verb conjugations and as such its inflected forms changed considerably over time, but that is more a topic of the evolution of the Quenya verb system itself.
