expel

This term conveys a sense of forceful removal, whether through official authority or physical pressure. When applied to people, it carries a heavy, punitive connotation, suggesting a permanent or formal severance of ties between an individual and an institution or state. In biological or mechanical contexts, the word describes the active discharge of substances. It differs from passive leaking or drifting by implying a deliberate or systemic push, such as the action of a pump or the respiratory system.
