demonstratiivisia

Demonstratiivisia is a Finnish adjective form meaning “demonstrative” and is used to modify nouns in a partitive plural construction. It is the plural partitive form of the base adjective demonstratiivinen, which denotes determiner-like or deictic reference such as “this” or “that” in relation to a noun.

In Finnish, adjectives inflect for number and case to agree with the noun they modify. For a noun in partitive plural, an adjective of the type -inen often takes the ending -isia. Thus, demonstratiivinen becomes demonstratiivisia when describing plural nouns in the partitive. This form appears in sentences where the object is indefinite or quantified and cannot be treated as a definite plural, or in predicative constructions requiring a partitive complement.

Usage examples include phrases like These are demonstratiivisia sanoja (These are demonstrative words) or Hän esittää demonstratiivisia argumentteja (He presents demonstrative arguments). The form signals a demonstrative function of the adjectives or pronouns used with the noun, while also conveying aspects of quantity or indefiniteness in the context of the sentence.

Compared to other forms of the same adjective, demonstratiivisia is specifically the partitive plural inflection. Other inflections of demonstratiivinen cover different nouns, numbers, and cases (for example, nominative plural demonstratiiviset, or genitive demonstratiivisten). Understanding demonstratiivisia helps in analyzing Finnish noun phrases that express deictic reference under partitive conditions.
