yhdenlainen

Yhdenlainen is a Finnish adjective meaning “of one kind” or “uniform.” It is used to describe something that lacks variety, being of a single type, form, or category. The term can appear in general descriptive language as well as in more analytical or technical writing to express sameness within a group or system.

Etymology: Yhdenlainen is formed from the genitive singular of yksi (yhden) combined with the suffix -lainen, which creates adjectives meaning “of the kind of.” The construction literally signals a single kind or type and is part of a broader family of Finnish descriptors built with -lainen.

Usage: The expression is most common in written Finnish, including academic, technical, and descriptive prose. It can describe objects, designs, policies, or classifications that show little or no variation. It contrasts with terms such as monimuotoinen (diverse) or monipuolinen (multifaceted). In phrases, it often appears as yhdennlainen ratkaisu (a single-kind solution) or yhdenlainen muoto (a uniform form). The nuance can be neutral or mildly evaluative, depending on context and tone.
