A neologism coined by Arael posted on 2023-11-21 in the Vinyë Lambengolmor Discord Server (VLDS), an inceptive u-verb based on √TUL “come”; compare [ᴹQ.] tulma “event”.
Quenya
lárë
happen
tullu-
verb. to occur, happen (i.e. come in time)
marta-
to chance
marta- (1) vb. "to chance" or *"happen" (QL:63), cf. mart- "it happens" (impersonal) (LT2:348 read marta-?). Another version assigns transitive meanings to the same verb: "to define, decree, destine" (with the last sense = martya-, q.v.), with a variant umbarta- "in more lofty senses" (PE17:104)
[lárë vb. "happen" (VT45:26; the word has an unusual shape for a verb, and was in any case deleted)]
