pluralisablatiiviseen

Pluralisablatiiviseen is a linguistic term used to describe the plural form of the ablative case in Finnish grammar. It refers to how the source or origin is expressed when the referring noun is plural. In descriptive grammars, this form is analyzed as the plural counterpart of the singular ablative (from, from out of). The concept is mainly encountered in linguistic descriptions and typology rather than in everyday grammar instruction.

In Finnish, the ablative/into-origin relation is expressed with suffixes such as -sta/-stä or -lta/-iltä, and the plural version signals the same relation for multiple entities. The plural ablative commonly appears in phrases that indicate coming from or originating among several things or groups. For example, forms such as kirjoista (from the books), taloista (from the houses), and ihmisistä (from people) illustrate how the plural ablative functions with different noun classes.

Morphology and usage are context-dependent. The exact ending can vary with vowel harmony and the phonology of the noun stem, and irregularities may occur with certain stems or consonant gradation. The plural ablative is thus described in grammars as a productive yet somewhat specialized inflection pattern that coexists with other plural and case forms.

Related concepts include the singular ablative, the elative, and other plural case forms. Pluralisablatiiviseen as a term helps linguists discuss and compare how plurality interacts with origin-marking across Finnish nouns, and it appears in cross-linguistic discussions of case systems as a way to categorize plural-origin expressions.
