Keskimäisen

Keskimäisen is a Finnish adjective form meaning central, middle, or median in a qualitative sense. It is the genitive singular form of the adjective keskimäinen, which is built from keski- “middle” with the suffix -mäinen to indicate a quality. As a grammatical form, keskimäisen is used whenever the modifying adjective appears with a noun in the genitive singular, for example: keskimmäisen arvon, keskimmäisen etäisyyden, keskimmäisen alueen.

In everyday language, keskimäisen is relatively uncommon compared with keskimääräinen, which more often translates to “average” or “mean.” Keskiarvo and keskimääräinen are the standard terms for arithmetic mean in statistics, while keskimäinen generally refers to a central or middle position within a set rather than a specific numeric average. Nevertheless, keskimäisen can appear in technical or formal prose describing central references, midpoints, or intermediate values.

Usage notes: keskimäisen follows normal Finnish adjective declension patterns and changes form to match number and case. Examples in the genitive singular include keskimäisen arvon and keskimäisen etäisyyden; the plural genitive would be keskimäisten arvojen or keskimäisten etäisyyksien, respectively.
