yläpuolisten

Yläpuolisten is a Finnish grammatical form that functions as the genitive plural of the adjective yl äpuolinen, used to refer to a group described as being on the “upper side” or “upper part” of something. It is not a standalone noun, but a case form that appears in noun phrases to indicate possession or association with the group described as the upper ones.

The construction combines the prefix yl ä- meaning “upper” with the suffix -puolinen, an adjective-forming element related to puolinen meaning “part/side.” In practice, yl äpuolinen describes something located on the upper part or relative to another part, and yl äpuolisten marks “of the upper ones” in contexts where the group is being distinguished from others, such as a lower counterpart or other divisions.

Usage is most common in descriptive, historical, or literary Finnish rather than everyday speech. It can appear in discussions of partitions, diagrams, or social descriptions where two or more groups are contrasted (for example, an upper subset versus a lower subset). Because it is a grammatical form rather than a widely used standalone term, its appearance tends to be limited to written texts and formal descriptions.

A related form is alapuolisten, the genitive plural of alapuolinen, referring to the “lower ones.” In contrast to ordinary adjectives, these inflected forms convey specific relational meaning about groups positioned in relation to one another.
