penetrable
Able to pierce
Penetrable describes something that can be passed through or pierced.
A penetrable barrier has gaps or weaknesses.
Penetrable defenses can be breached.
Penetrable fog allows some visibility.
The word often implies vulnerability—what can be entered can be compromised.
Figuratively, a penetrable mystery yields to investigation; a penetrable mind is open to influence.
