permeates

Permeates is the third-person singular present tense of the verb permeate. It describes the action of spreading or diffusing through something, or the state of being present throughout a space or material. The term is used in science to refer to substances passing through or diffusing within membranes or porous media, and in everyday language to describe how scents, ideas, or influences spread and become evident throughout a place or system.

Etymology and scope: Permeate derives from Latin permeare, meaning to pass through, formed with per- “through” and meare as a root related to moving through. The sense of permeates is broadly figurative as well as physical, applicable to liquids, gases, and intangible phenomena such as cultures or policies that become pervasive.

Usage: In scientific contexts, permeates describes diffusion or permeation through barriers, such as a solvent permeating a polymer membrane or water permeating soil. In literary or rhetorical contexts, it can describe how a mood, cultural norms, or institutional changes permeate an organization or community.

Limitations: Permeation depends on factors including concentration gradients, temperature, pressure, and the permeability of the material. Not all substances or ideas will permeate equally; some barriers or resistances can limit spread.

Related terms: permeation (the process itself), permeable (capable of being permeated), impermeable (not permitting passage). Permeates often conveys a sense of thorough, pervasive spread.
