prevent
This word conveys a sense of proactive intervention to ensure a specific outcome does not occur. It differs from stop, which often describes interrupting an action already in progress, by focusing on the anticipation of an event to keep it from starting in the first place. In medical and legal contexts, it carries a strong connotation of systemic or strategic avoidance. It is frequently paired with the preposition from, creating a structural barrier between the subject and the prohibited action.
Meanings

"The new law is designed to prevent tax evasion."
