Etymology

prevent = pre<before> + vent<come>

  • pre: From Latin prae-, meaning "before" (temporal or spatial).
  • vent: From Latin venire, meaning "to come."

Etymology Origin:
The word "prevent" originates from Latin praeventus (past participle of praevenire), combining prae- (before) and venire (to come). It originally meant "to come before" or "anticipate," later evolving to imply "acting in advance to stop something." This reflects the logic of interception—arriving ahead of an event to block its occurrence.
