teorioissa

Teorioissa is the inessive plural form of the Finnish noun teoria, meaning “in theories.” It is used to refer to content, ideas, or structures that exist within multiple theories, rather than in a single theory. The term is common in academic Finnish, especially in philosophy, social sciences, and comparative studies, where discussions often contrast how different theories explain a phenomenon.

Formation and grammar: Teorioissa is formed by taking the plural stem of teoria and inflecting it to the inessive case to indicate location or context inside theoretical frameworks. It denotes a plural, non-physical space and is typically used with verbs and constructions that discuss theories in general terms or as part of a comparative analysis. It contrasts with teorian or teorian sisällä in other grammatical forms.

Usage examples:

- Eri teorioissa on erilaisia oletuksia. (In different theories there are different assumptions.)

- Tutkimuksessa verrataan teorioissa esiintyviä malleja. (The study compares models that appear in theories.)

- Filosofisissa keskusteluissa teorioissa korostetut käsitteet voivat johtaa erilaisiin johtopäätöksiin. (In philosophical discussions, concepts emphasized in theories can lead to different conclusions.)

Etymology and related forms: teoria is a loanword from Latin theoria, via other languages. The form teorioissa is the plural inessive, used when speaking of multiple theories. Related forms include teoria (theory) in other cases and teorioita (partitive plural, “theories”).
