Interspatial

Interspatial is an adjective used to describe phenomena, relations, or structures that occur between spaces. In general, it refers to the properties or interactions that exist in, or pertain to, the region separating defined spaces, objects, or domains.

The term derives from the Latin inter- meaning between and spatium meaning space. It is a relatively uncommon term in everyday use and is more likely to appear in specialized discussions of spatial organization or theory.

In geography and urban planning, interspatial analysis examines relationships between distinct spatial regimes, such as urban and rural areas or different jurisdictional spaces. In materials science and geology, writers may refer to interspatial porosity or interspatial voids to describe openings between grains or minerals. In biology and medicine, “interspatial” sometimes appears in descriptions of spaces between cells or tissue components, though “interstitial” is the more standard term. In philosophy and cognitive science, interspatial concepts may be used to discuss how spaces relate across scales or between agents, including the notion of space that exists between objects rather than within them.

Because “interspatial” is not widely standardized, its precise meaning can vary by discipline and author. When precision is required, readers may prefer more established terms such as interstitial, interspace, or spatial-relational descriptors.
