permeable

This term describes a physical property of porosity, where a material allows substances to seep through its structure. It is most frequently encountered in scientific contexts, such as biology or geology, to describe membranes or soil layers that facilitate the movement of fluids. In a social or intellectual sense, the word describes a state of openness. It suggests a boundary that is not rigid, allowing external influences, ideologies, or cultural shifts to enter and alter the internal state of a system or organization.
