peruspiiriin

Peruspiiriin is the illative form of the Finnish noun peruspiiri, a compound of perus- (basic, fundamental) and piiri (district, circle, area, circuit). The term is used in contexts where something is directed toward, or included in, a basic geographic or functional unit known as a peruspiiri. Its meaning is thus context-dependent and often relates to planning, administration, or data organization within a defined area.

Etymology and form: Peruspiiri combines perus- with piiri to form a unit meaning “basic district.” The suffix -iin marks the illative case, which indicates direction into or toward something. Therefore peruspiiriin translates roughly as “into the basic district” or “to the basic district.”

Usage and context: In Finnish public administration, planning, and technical language, peruspiiriin is used to indicate inclusion within a basic district or actions taken with respect to that district. There is no single nationwide definition of a peruspiiri; its exact scope is determined by the organization or sector using the term. Typical contexts include planning and budgeting within a basic district, data aggregation at the district level, or directing services and resources to the basic district.

Examples:

- Tietoja kerätään peruspiiriin. (Data are collected into the basic district.)

- Palvelut suunnataan peruspiiriin. (Services are directed to the basic district.)
