partitiivisissa

Partitiivisissa is a Finnish grammatical term describing a specific inflected form of the adjective partitiivinen, meaning “partitive” or “pertaining to the partitive case.” In Finnish, adjectives agree with the nouns they modify in number and case, so the adjective partitiivinen appears in various inflected forms to match the noun.

The form partitiivisissa is the inessive plural of partitiivinen. It is used when the noun it modifies is plural and in the inessive case, which marks a location or state of being “in” something. Therefore, partitiivisissa functions as an attributive modifier preceding a plural noun in the -issa/-issä form. The corresponding singular inessive form is partitiivisessa, and the nominative plural related forms are partitiiviset, etc.

In usage, partitiivisissa occurs primarily in linguistic descriptions and grammar explanations, or in advanced Finnish language materials that illustrate agreement across number and case. It is not a separate lexical item with independent meaning, but a grammatical inflection. The form may appear in sentences describing the properties of phrases or in corpus analyses, for example discussing “partitiivisissa kirjoissa” or “partitiivisissa lauseissa” as categories of examples; however, everyday Finnish typically does not require invoking this exact form outside of grammatical discussion.
