What Does “Porous” Mean? An In-Depth Explanation
Porous is an adjective used to describe materials or surfaces that contain tiny holes or pores, which allow liquids, gases, or small particles to pass through.

- Metaphorical uses describe anything that’s permeable, flexible, or not airtight, like laws or barriers.
- The degree of porosity can vary: from slightly porous (barely permeable) to highly porous (easily penetrated).
