leviävissä

Leviävissä is a Finnish word formed from the verb leviää (to spread) and the present active participle suffix -vä. It is the participial form that functions as an adjective and is inflected in the inessive plural to describe something that is in a state of spreading or that is capable of spreading. The base idea is “spreading” or “contagious,” and the form is used in contexts where a noun is described as being in that condition.

In practice, leviävissä is most common in formal or technical language, such as epidemiology, biology, or discussions of information and influence spreading. It often appears in phrases where the noun is accompanied by a relative or stative clause, for example, leviävissä olevat ilmiöt (phenomena that are spreading) or leviävissä oleva tauti (a contagious disease). The word emphasizes the ongoing process or potential of spread rather than a finished state.

Relation to related terms: leviävä is the basic present active participle meaning “spreading” or “contagious,” used more simply to qualify nouns (leviävä tauti, a spreading/contagious disease). Leviävissä is a grammatically specific form used in contexts that require the inessive plural or a particular attributive construction. The concept is closely tied to discussions of transmission dynamics and contagion, and is contrasted with non-spreading descriptors in everyday Finnish.
