teoreettisissa

Teoreettisissa is a Finnish grammatical form rather than a standalone concept. It is the inessive plural form of the adjective teoreettinen, meaning theoretical. In Finnish, adjectives agree with the nouns they modify in number and case, so teoreettisissa appears whenever the noun is plural and in the inessive case, typically translated as “in the theoretical …” or “in theoretical …” contexts.

The form is used in academic and scientific writing to describe plural nouns that are situated within theoretical frameworks, models, or contexts. It contrasts with teoreettiset (nominative plural, “theoretical” as a plural adjective) and with teoreettisessa (singular inessive). The corresponding adverb is teoreettisesti, meaning “theoretically.”

Common contexts for teoreettisissa include phrases such as teoreettisissa malleissa (in theoretical models), teoreettisissa viitekehyksissä (in theoretical frameworks), or teoreettisissa perusteissa (in theoretical grounds). Its usage signals that the discussion focuses on concepts or constructs defined within theory rather than empirical observations.

Etymology traces the form to the root teoreettinen, derived from teoria, the Finnish word for theory, with the typical -inen adjective ending. As a grammatical inflection, teoreettisissa does not convey any standalone meaning beyond indicating “in the/theoretical [plural noun]” and must be linked to a noun in a sentence.

In summary, teoreettisissa is a standard Finnish inessive plural adjective form used to refer to theoretical aspects in plural contexts.
