genetiivillisen

Genetiivillisen is a Finnish adjective meaning “genitive-related” or “pertaining to the genitive.” It is the genitive singular form of the adjective genetiivillinen, which is used in linguistic and grammatical contexts to describe features connected to the genitive case. The base term genetiivillinen derives from genetiivi, the Finnish word for “genitive,” itself borrowed from Latin genetivus via Swedish genitiv. The suffix -inen marks the adjective, and -isen is the genitive singular form.

In Finnish grammar, adjectives agree with the noun they modify in case and number. For adjectives ending in -inen, the genitive singular form typically ends in -isen, yielding genetiivillisen as the form used when the noun is in the genitive case. Examples include genetiivillisen muodon (the form of the genitive) or genetiivillisen nimen (the genitive form of the name). In plural, the corresponding forms would be genetiivillisten to match genitive plural nouns.

Usage of the term is mainly found in linguistic descriptions, grammars, and language-learning materials. In everyday Finnish, speakers rarely reference genetiivillisen outside of grammatical analysis or theoretical discussion. The concept helps describe how adjectives inflect to reflect the genitive relationship and how such inflection interacts with noun forms.
