kotiseutunsa

Kotiseutunsa is a Finnish expression that literally means "one's own home region" or "the home region of someone." It is formed from kotiseutu, meaning home region, plus the third-person possessive suffix -nsä, and is used to indicate the home region belonging to the person referred to.

In usage, kotiseutunsa denotes a sense of local belonging and regional identity. It is commonly applied when describing dialects, local traditions, landscapes, or memories connected to a particular area. The concept often appears in discussions about how people relate to their birthplace, their place of upbringing, or other areas with which they have long-standing ties.

Cultural and educational contexts mark kotiseutu as an important element of Finnish local history and identity. Kotiseututyö, a form of local-history work in schools and communities, encourages people to explore, document, and preserve their kotiseutunsa and regional heritage. Organizations such as Kotiseutuliitto promote the study and appreciation of local history and culture across Finnish regions.

See also related terms such as kotiseutu, the broader concept of a home region, and Kotiseutuliitto, the federation dedicated to local-history activities. The phrase kotiseutunsa can thus function as a linguistic marker of personal or communal ties to a specific geographic area.
