Numeraalisten

Numeraalisten is a Finnish inflected form, the genitive plural of the adjective numeraalinen. In Finnish morphology adjectives that end in -inen typically form the genitive plural by replacing -inen with -isten, so numeraalinen → numeraalisten. The form is used to mark possession, association or qualification when the modified noun is plural, for example in phrases that mean "of the numeral-related (things)" or "of the numerical (plural items)."

The adjective numeraalinen commonly describes things related to numerals or numeral systems (words or expressions that denote numbers), and is distinct from numeerinen, which more often describes numeric or quantitative properties in a mathematical or computational sense. In context, numeraalisten is paired with a following noun in the partitive or nominative plural depending on syntactic requirements: for instance, numeraalisten sanojen käyttö ("the use of numeral words") or numeraalisten järjestelmien rakenne ("the structure of numeral systems").

As a grammatical form it illustrates Finnish nominal and adjectival inflection patterns and is encountered in linguistic descriptions, pedagogical texts, and general language use when discussing categories, properties or possessions of plural entities described as numeraalinen.
