aritmetisen

Aritmetisen is a Finnish adjective meaning arithmetic. The form aritmetisen is the genitive singular of the adjective, used to modify a noun in the genitive case, as in aritmetisen luvun, meaning “of the arithmetic number.” Like other Finnish adjectives, aritmetinen agrees with the noun it describes in number and case, so its endings change across contexts (for example aritmetinen luku, aritmetisen luvun, aritmetisen laskennan).

Etymology and usage context: Aritmetinen derives from aritmetikka, the Finnish term for arithmetic, formed with the standard -inen suffix that turns a noun or root into an adjective. In mathematical and educational language, the adjective appears in phrases describing arithmetic concepts, procedures, or objects. It is commonly paired with nouns such as laskenta, luku, and logiikka to form standard terms like aritmetinen laskenta (arithmetic calculation), aritmetisen luvun neliö (the square of an arithmetic number), or aritmetisen logiikan periaatteet (the principles of arithmetic logic).

Function in language: The word functions as a determinant describing the type of object or concept. It is not a standalone field or discipline; rather, it modifies the noun to specify that the reference pertains to arithmetic rather than geometry, algebra, or other branches of mathematics. The related noun forms and grammatical cases follow regular Finnish adjective inflection rules.

See also: Aritmetikka, geometrinen, algebrinen, looginen logiikka. These terms provide context for comparing arithmetic with other mathematical domains and logical frameworks.
