writhe

Writhe wound its way to English from the Old English verb wrīthan ("to twist") and is akin to the Old English verb wrigian ("to turn or go"). Wrigian gave us our words wriggle, awry, and wry. When something wriggles it twists from side to side with quick movements, like an earthworm. When something goes awry, its twists or winds off course, or toward catastrophe. Wry can mean "bent or twisted" but now usually implies clever, ironic humor. Nowadays, writhe often suggests the physical contortions one makes when enduring crippling pain or when trying to extract oneself from a tight grasp (as an animal from a predator's claws). Alternatively, it can imply an emotionally wrenching feeling (as of grief or fear) from which one seeks relief.
