spillsover

Spillsover is a term that occasionally appears in texts as a variant spelling of spillover or as a proposed neologism to describe cross-domain propagation of effects. The central idea associated with spillsover resembles spillover: perturbations, signals, or costs originating in one domain spreading to others. Because spillsover is not widely standardized in academic writing, most references rely on the established term spillover, and the spelling can vary by author or publication.

In practice, spillsover would be used to emphasize cross-domain or cross-timeline diffusion, including delayed effects or geographic spillovers. In ecology and epidemiology, spillover traditionally describes the transmission of pathogens from animal reservoirs to humans or the movement of ecological effects across ecosystems. In economics and policy, spillover or externalities describe how outcomes in one sector or country influence others. If treated as spillsover, the term is typically intended to foreground the broader reach of an initial disturbance and the potential for cascading consequences beyond the originating system.

Examples of spillsover-style thinking might include a regional drought raising food prices in distant markets, or a cyber vulnerability in a software library triggering cascading outages in multiple dependent systems. In each case, the emphasis is on interconnectedness and the transfer of impact beyond the primary target.

Notes: spillsover is not a core term in major dictionaries; when encountered, it is often best understood as a variant or a deliberate emphasis on cross-domain spillover. See also spillover, externality, cross-domain impact.
