Why this word is great
CIENEGA — [Noun] A marshy spring where groundwater bubbles to the surface, particularly in the arid regions of the American Southwest. From Spanish ciénega ("marsh, swamp"), a term whose meaning sharpened in the desert into a life-saving particular. Unlike "swamp" (a broad, often forested expanse of stagnant water) or "fen" (a cool, peat-accumulating wetland of northern climes), a ciénega is a specific and improbable mercy. It is the sudden coolness underfoot on a baked hillside, the emerald shock of rushes against sun-bleached caliche, and the low, persistent music of water seeping over stone. In a landscape defined by thirst, it is the desert's quiet confession: a secret kept, and then, quietly, told.
