In literature the word “pervious” is often employed to evoke a sense of penetration or openness, whether referring to physical materials or more abstract qualities in character and circumstance. It is used to describe substances that allow the passage of light, air, or water—such as stone or fabric that admits light or moisture [1, 2, 3, 4]—while at the same time serving a metaphorical function to indicate a person’s receptivity or vulnerability to ideas and emotions [5, 6, 7]. Additionally, its technical usage extends into fields like medicine and engineering, where it denotes the capacity of bodily passages or constructions to permit fluid movement [8, 9]. This multiplicity of meanings enriches both descriptive and figurative language, allowing writers to draw upon a precise sense of permeability in varied contexts [10, 11].
