What does preventable mean?
Preventable is an adjective describing something that could have been stopped, avoided, or kept from happening. It is especially common in reports and public discussion of accidents, injuries, crime, disease, waste, and technical errors. The word often carries an implication of responsibility: when an outcome is described as preventable, it suggests that appropriate action or better planning could have prevented it. It differs from preventive, which describes a measure designed to stop a problem, and from unavoidable, which indicates that no effective means of prevention exists. In everyday use, preventable can sound more formal than avoidable, but it provides a clear focus on whether prevention was possible. The word is frequently paired with nouns such as accident, death, error, damage, and failure.

Where does preventable come from?
Preventable was formed in English by adding the suffix -able to prevent. Prevent comes through French from Latin praevenire, a compound of prae- meaning “before” and venire meaning “to come,” originally referring to coming before or arriving ahead of someone. Over time, the word developed the sense of stopping or forestalling an event, and the later derivative preventable means capable of being stopped.
