crumble

This word evokes a sense of gradual disintegration or a sudden collapse of structure. When applied to physical objects, it suggests a brittle failure where a solid mass turns into small, irregular grains or fragments, often implying age, dryness, or fragility. In a psychological or social sense, it describes the failure of something that seemed stable, such as a person's composure or a political empire. This transition from strength to weakness is typically viewed as an inevitable result of mounting pressure or internal decay.
