adessiiviin

Adessiiviin is a term used in Finnish grammar to describe a specific inflected form of the word adessiivi, the name of the adessive case. In linguistic descriptions, adessiiviin is encountered when discussing how the noun adessiivi can be marked for a particular grammatical function in a theoretical or dictionary context. It is not a form that appears in everyday speech outside of grammars, typologies, or linguistic examples.

The form adessiiviin is formed by applying a suffix to the base noun adessiivi in order to create an illative or directional variant of the term within analytical tables. The essence of the concept is to reference the adessive case in a way that highlights its relationship to other cases in a morphological paradigm. Because it concerns terminology used in description rather than ordinary usage, adessiiviin serves mainly as a data point in grammar discussions rather than a word used in ordinary communication.

In practice, adessiiviin may appear in grammar explanations, inflection charts, or scholarly discussions where the aim is to illustrate how Finnish cases are named, declined, and related to one another. It helps learners and researchers distinguish between the label of a case (adessiivi) and the various inflected forms that can be used when describing or indexing grammatical phenomena.
