Adverbiaalisiin

Adverbiaalisiin is a grammatical form used in Finnish linguistics. It is the illative plural form of the adjective adverbiaalinen or, in some descriptions, of the noun/adjective adverbiaali when referring to multiple instances of adverbials. The term appears mainly in scholarly texts and descriptive grammars rather than in everyday language.

Formation and meaning. The base concept is adverbiaalinen, meaning “adverbial,” or adverbiaali, meaning “an adverbial element.” When describing several such elements, Finnish uses the illative plural ending, producing adverbiaalisiin. This form marks a direction toward or into a group of adverbials in the grammatical sense, and it is typically encountered in lists, classifications, or analytical examples within grammar discussions.

Usage in linguistic description. Adverbiaalisiin is used to talk about sets of adverbials or adverbial expressions as a unit. For example, a study might refer to adverbiaalisiin ilmaisuisiin kuuluvat ajan ja paikan ilmaukset, meaning “adverbial expressions belonging to the group of time- and place-related expressions.” Because it is a technical term, the form is most common in theoretical or descriptive contexts rather than in everyday Finnish prose.

Relation to related terms. The related concepts include adverbiaalinen (adverbial, as an adjective) and adverbi(a)ali (an adverbial element or word). Adverbiaalisiin thus sits at the intersection of these terms, signifying the plural illative case of the category when discussing multiple adverbials in linguistic analysis.
