What does unpreventable mean?
Unpreventable is an adjective meaning impossible to prevent, avert, or stop. It is commonly applied to accidents, disasters, failures, events, and circumstances in which no effective intervention could have changed the outcome. The word emphasizes the lack of a successful means of prevention and may suggest that responsibility or blame is limited, although it does not automatically remove responsibility from those involved. In everyday English, unavoidable is more frequent and can describe both outcomes that cannot be escaped and situations that cannot be circumvented. Unpreventable often has a more specific or technical focus, particularly when discussing an event whose occurrence or consequences were beyond human control. The related adverb is unpreventably, as in “the system failed unpreventably.”

Where does unpreventable come from?
Unpreventable was formed in English by combining the prefix un- with prevent and the suffix -able. The word prevent comes through Old French from Latin praevenire, from prae- “before” and venire “to come,” originally meaning “to come before” or “anticipate.” English developed prevention, preventive, and the variant spelling preventible from the same Latin root.
