Jokinlainen

Jokinlainen is a Finnish adjective and determiner meaning "some kind of" or "a certain kind of." It is used to describe a noun without specifying its exact type, conveying vagueness about which member of a category is meant. It is common in everyday language and in writing when an exact label is not given.

The form combines jokin (some, certain) with the suffix -lainen, which creates adjectives describing a kind or type. The result is a single word jokinlainen that functions as an attributive adjective before a noun, for example jokinlainen ratkaisu.

As an adjective, jokinlainen follows standard Finnish agreement and declines with the noun in number and case: nominative singular jokinlainen ratkaisu; genitive singular jokinlaisen ratkaisun; partitive plural jokinlaisia ratkaisuja.

Usage notes and related terms: jokinlainen expresses vagueness; eräänlainen conveys a more definite sense of "a certain kind" and is often more formal. The terms jokinlainen and eräänlainen can sometimes be used interchangeably but carry subtle differences in nuance. In practice, jokinlainen is common in casual speech, while eräänlainen may appear in more formal or generalized contexts.

Examples:

- Tämä on jokinlainen ratkaisu ongelmaan.

- Hän on jokinlainen asiantuntija.
