Lähteisen

Lähteisen is a Finnish surname. Its etymology is thought to derive from the word "lähde," meaning "spring" or "source" in Finnish, often referring to a natural water spring. The suffix "-inen" is a common Finnish adjectival and possessive ending, implying a connection to or origin from a spring. Therefore, the surname likely indicated that a person or their ancestors lived near a spring or originated from a place named after a spring.

As a surname, lähteisen is not particularly widespread but is found primarily in Finland. Like many Finnish surnames, it became more standardized during the late 19th and early 20th centuries when there was a national movement to adopt more distinctive Finnish names, often based on nature or personal characteristics. Individuals bearing the surname lähteisen can be found in various regions of Finland and among the Finnish diaspora. Its usage and recognition are primarily confined to Finnish cultural contexts.
