Demostraatioihin

Demostraatioihin is the illative plural form of the Finnish noun demonstraatio, meaning demonstrations, typically public protests or displays. The word is a loanword from Latin demonstratio and appears in Finnish with spellings such as demonstraatio or demonstraatio, depending on historical and stylistic usage. The illative suffix -ihin marks direction toward or participation in multiple demonstrations, as in the example: Joukko kansalaisia suuntautui demostraatioihin kaupungin keskustaan.

In contemporary Finnish the more common term for a street protest is mielenosoitus. Demostraatio is used in more formal, historical, or technical contexts, and may also refer to a demonstration in a broader sense, such as a mathematical or logical demonstration (proof). The illative plural demostraatioihin illustrates how Finnish forms expressions that indicate movement toward or involvement in several demonstrations.

Etymology and usage notes: the word derives from Latin demonstratio meaning proof or demonstration. In Finnish it has been incorporated in slightly different spellings and can function in both social and scholarly vocabularies. The term remains distinct from mielenosoitus in everyday language, while overlapping with scientific or philosophical uses where a “demonstration” or “proof” is meant.
