adessivemarked

Adessive-marked refers to noun phrases that bear the adessive case marking, a grammatical category used in some languages to indicate location on or at a surface or site. It is part of locative or spatial systems found in various language families, most notably the Finnic languages, where adessive forms a distinct case with its own suffixal marking.

The primary semantic function of the adessive is to express location in a surface-oriented or at-a-location sense, roughly equivalent to “on,” “at,” or “on top of” in English. In languages with a dedicated adessive case, this marking is typically expressed through a specific suffix attached to the noun. The adessive may also interact with other grammatical layers such as possession, reference to a location, or idiomatic expressions, depending on the language.

Morphological realization can vary. In Finnish, the adessive is realized with the suffix -lla/-llä, with form depending on vowel harmony and the stem structure of the noun. For example, pöytä (table) becomes pöydällä to mean “on the table,” as in Kissa on pöydällä (“The cat is on the table”). Similar surface-location marks exist in closely related Finnic languages, though the exact form and usage can differ. In other language families, adessive-like meanings may be expressed by prepositions or postpositions rather than a single productive suffix.

Cross-linguistic usage varies: some languages have a robust adessive case as part of a larger locative system, while others convey similar meanings with separate locative particles or periphrastic constructions. The term adessive, and its marked form, are primarily of interest in descriptions of languages with explicit locative case inventories and are often studied alongside related cases such as inessive, allative, and illative.
