osaalueella

Osaalueella is a Finnish locative form used in geography, urban planning, and statistics to indicate that something is located in or on a subarea of a larger area. The word is built from osa-alue (subarea) with the adessive suffix -lla, yielding "on the subarea" or "in the subarea." It is commonly found in official documents, maps, and reports describing the distribution of population, land use, or facilities within a city or municipality.

Usage and function: As a phrase, osaalueella modifies a verb or clause indicating location. Example sentences include: "Koulut sijaitsevat osa-alueella X." (The schools are located in subarea X.) "Osa-alueella asuu noin 2 500 ihmistä." (About 2,500 people live in the subarea.) In many cases the subarea is defined by a boundary or code within the larger area.

Linguistic notes: It is a standard example of a compound noun with a locative case. The base "osa-alue" refers to any subordinate division such as districts or zones. The form changes with case, for instance osa-alueelle (onto the subarea) or osa-alueelta (from the subarea).
