adessiivisista

Adessiivisista is a linguistic term used in Finnish to refer to the plural partitive form of the noun adessiivi. The adessiivi itself is a grammatical case used to express location on or at something, typically marked in Finnish by endings such as -lla or -llä (for example pöydällä, meaning “on the table”). The plural forms of the adessiivi include adessiivit in the nominative plural, and adessiivisista in the plural partitive.

In linguistic description, adessiivisista muodoista or adessiivisista is often used to discuss multiple instances of the adessive case or the adessive forms in general. The term serves to distinguish discussions about several adessive forms from a single-adessive instance. The partitive plural ending -ista/-istä is a productive suffix in Finnish, and here it combines with adessiivi to yield adessiivisista as the grammatical form needed when the head noun is in partitive plural.

Examples of usage include phrases such as adessiivisista muodoista, meaning “from the adessive forms,” or adessiivisista käytöistä, meaning “from the adessive uses.” These constructions appear primarily in grammar descriptions, typological studies, and language data analyses, where precise reference to plural case forms is required.

Relation to other cases is straightforward: adessiivi denotes location (on, at), while other cases such as inessiivi, illatiivi, or ablatiivi express related locational or directional meanings. Adessiivisista therefore belongs to the broader discussion of how Finnish marks spatial relations across number variants.
