MARCOUR — [Noun] A state of withering or wasting away; a gradual, atmospheric leanness. From Latin marcor, "a wasting away, decay," from marcēre, "to wither." Unlike emaciation, which denotes the stark result of acute privation, or atrophy, which specifies the clinical decline of a tissue, marcor is the quiet, pervasive process of corporeal diminishment. It is the parchment skin of an old library book, the slow retreat of flesh from the back of a hand, the profound leanness of an apple left on a bare branch. Marcour is the patient grammar of subtraction, the shape left when presence becomes memory.
