Etymology

Origin of prevention

1520–30; < Late Latin praeventiōn- (stem of praeventiō ) a forestalling. See prevent, -ion

Explanation

When an action stops something from happening, like assigning extra teachers to watch a playground during recess to prevent bullying, it's called prevention. The noun prevention comes up most often when people are trying to keep something bad in check, like crime, disease, or forest fires. Educating kids about nutrition is one form of obesity prevention, for example, and lowering speed limits can help with accident prevention. The word prevent is at the root of prevention, and it comes from the Latin praeventus, "anticipate or hinder."
