Morphology

prevent = vent (opaque) = pre + vent

Although analyzable as Latin pre- + ven- (come), the element 'vent' is not a productive English base meaning 'come', so learners cannot reliably derive the meaning from its parts.

Etymology

Prevent comes from the parts pre- ('before') and venire ('to come'), the same root in event, a thing that 'happens'. So to prevent something is to 'come before' it and stop it from happening.
