mairë

noun. art, work of high and beautiful art, process of producing an art work

A word in Quenya Notes (QN) from 1957 that Tolkien described as meaning “a work (or the process of producing a work) of high and beautiful art” based on the root √MAY “make (in artistic sense)” (PE17/163). It thus has most of the same meanings as English “art”.
