bellow

This word evokes a sense of raw, guttural power and volume. When used to describe a human voice, it suggests a lack of refinement or a loss of control, typically associated with authority, rage, or extreme distress. It differs from a scream or a yell by its deep, resonant quality, mimicking the sound of a bull. As a mechanical object, the term refers to the expanding and contracting action of air. In this context, it describes a specific tool used in traditional metallurgy or organ pipes, where the physical movement of the device creates a forced stream of air.
