epidemiologiseen

Epidemiologiseen is a Finnish inflected form of the adjective epidemiologinen, which means "epidemiological" or "relating to epidemiology." It appears when the adjective agrees with a noun in the illative case, expressing movement or direction "into" something (for example, into a study, context or category). The form reflects standard Finnish adjective declension patterns, particularly for adjectives ending in -inen, which take -seen in the singular illative (compare tieteellinen → tieteelliseen).

Etymology traces the base term epidemiologinen to international scientific vocabulary derived from Greek roots (epi- "upon", demos "people") via modern languages and Finnish formation conventions (-logia → -loginen meaning "-logical/related to"). The inflected epidemiologiseen therefore combines the lexical stem with Finnish morphological case marking used to coordinate with nouns.

Typical usage occurs in phrases such as epidemiologiseen tutkimukseen osallistua ("to participate in an epidemiological study") or epidemiologiseen analyysiin viitata ("to refer to an epidemiological analysis"). It is grammatical rather than lexical, and does not function as an independent noun; its role is to modify a following noun that is in the same illative case.

Understanding epidemiologiseen is useful for reading Finnish scientific texts, reports and news that describe movement into or focus on epidemiological contexts.
