geologisissa

Geologisissa is a Finnish inflected form of the adjective geologinen, meaning geological. It is used to modify plural nouns in the inessive case, typically translating to “in geological …” or “geological …” in English. The form appears when the noun it describes is plural and located in a context such as studies, formations, or locations.

In practice, geologisissa accompanies plural nouns to situate statements within the field of geology. For example, geologisissa tutkimuksissa means “in geological studies,” and geologisissa muodostumissa means “in geological formations.” The form reflects both number (plural) and case (inessive), and it agrees with the noun it modifies.

Usage notes and stylistic considerations: Geologisissa is common in academic and scientific Finnish, especially in geology, geoscience reports, and descriptive passages about geological phenomena. Because it is an adjective form, it does not stand alone; it always precedes a plural noun in the inessive. When referring to a single object or to a general concept, other inflected forms of geologinen are used (for example, geologinen tutkimus for “a geological study” in nominative singular).

Relation to related terms: The base adjective is geologinen. Other inflections include geologiset (nominative plural), geologisia (partitive plural), geologiseen (illative singular), and geologisiin (illative plural). The noun form for the science is geologia (geology), and a practitioner is geologi (geologist).
