Teinen

Teinen is a proper noun that can refer to more than one use in Finnish- and Nordic-language contexts. In onomastics, Teinen most often appears as a surname of Finnish origin. The name is formed with the common Finnish surname suffix -nen, which frequently transforms a base into a form suggesting descent or a diminutive relation. The precise root of Teinen is not consistently attested in standard reference works, and the surname may have derived from a personal name, a toponym, or another noun.

Teinen may also occur as a place name or toponymic element in Nordic locales, following patterns where -nen is used in locality names. As a place name, its usage tends to be limited and local to specific regions; such instances, when present, are typically in areas with historical Finnish or broader Scandinavian settlement.

In contemporary use, Teinen appears in records and genealogical materials associated with Finnish-heritage communities. It is not widely distributed as a given name, and no widely known public figures with this surname are documented in major encyclopedic sources.
