reaalisen

Reaalisen is the genitive singular form of the Finnish adjective reaallinen, meaning real or genuine. It is not a standalone term but a grammatical form used to link a noun in the genitive case to the idea of realness. For example, rea alisen elämän ongelmat means “the problems of real life,” rea lisen maailman odotukset means “the expectations of the real world,” and rea alisen tutkimuksen tulokset means “the results of real-world research.”

In Finnish, adjectives inflect for case and number. The base form is rea allinen (nominative singular). The genitive singular form is rea alisen, the plural nominative is reaaliset, and the genitive plural is reaalisten. These forms allow the adjective to describe a wide range of nouns while indicating the relationship to the real or actual domain.

Usage and nuance: reaallinen denotes something empirical, tangible, or actual, as opposed to theoretical or fictional. It often contrasts with terms like teoreettinen (theoretical) or fasil? imaginary concepts. In mathematics, the standard term for real numbers is reaaliluku, while the adjective reaalinen can appear in phrases such as rea lisen luvun arvo, meaning “the value of a real number.” The noun form reaali exists in Finnish to denote real-world objects or everyday material from teaching contexts (realia).
