matemaattisessa

Matemaattisessa is the inessive singular form of the Finnish adjective matemaattinen, meaning mathematical. In Finnish, adjectives agree with the nouns they modify in number and case, so matemaattisessa is used when the noun is in the inessive case. It is common in phrases such as matemaattisessa mielessä (in a mathematical sense) or matemaattisessa kontekstissa (in a mathematical context). By itself the word is not a standalone noun; it functions as an grammatical modifier within a larger phrase.

Etymology and form: matemaattinen derives from matematiikka (mathematics) with the typical -inen adjectival suffix. The inessive singular form matemaattisessa is produced by attaching the inessive ending -ssa/-ssä to the adjective stem. Finnish adjectives decline to reflect the grammatical role of the noun they describe, so other cases yield forms like matemaattisen (genitive) or matemaattista (partitive).

Usage: In academic and technical Finnish, matemaattisessa signals that a statement, reasoning, or context is based on mathematical principles. It often appears in discussions of theories, models, proofs, or comparisons where a mathematical perspective is being emphasized.
