Why this word is great
CLUSE — [Noun] A defile or narrow gorge that cuts transversely through the rock of an otherwise continuous ridge. From Old English clūse ("narrow pass, enclosure"), related to 'close', and borrowed from French cluse, ultimately from the Latin clausa ("a shut place, enclosure"). Unlike a generic "defile," a general term for any constricted mountain pass, or a broad "valley," a sunlit trough between ranges, a cluse is a specific act of geological defiance—a river's stubborn, perpendicular incision through a wall that geography intended to be unbroken. It is the startling gash through the spine of the Jura, the shadowed slit in a limestone ridge where cold air pools even at noon, and the water-worn keyhole framing a sudden window of distant light. One passes through not merely over or around, feeling the weight of the ridge momentarily concede—a brief, negotiated peace in the landscape's enduring war.
