reunainen

Reunainen is a Finnish term that can function as an adjective meaning "bordered" or "edge-related" and is also used as a Finnish surname. The root is the noun reuna, meaning edge or border, combined with the adjectival suffix -inen, which is common in Finnish for forming descriptors. In contemporary Finnish, reunainen is used to describe objects, regions, or abstract concepts that have clearly defined boundaries, for example a reunainen alue (bordered area) or a reunainen maisema (edge-facing landscape). The form can also appear in compound nouns or descriptive phrases.

As a surname, reunainen is rare. It appears among Finnish records as a family name, though it is not widely represented in public or historical figures. The more common surname variants include reunanen, which is derived from the same root but with a different suffix pattern.

Because reunainen has limited attestation as a proper noun, there are no widely recognized individuals or institutions associated with it in major encyclopedic sources. The term is primarily encountered in linguistic or onomastic discussions about Finnish adjective formation and surname patterns.
