regionaaliset

Regionaaliset is a Finnish adjective form used to describe things that pertain to a region or multiple regions. It is the plural form of regionaalinen when used as a modifier, and can also function as a noun in certain contexts. The word is built from the stem region- with the -aalinen suffix that is common for Finnish adjectives indicating relation or belonging to a geographic area.

In practice, regionaaliset is widely found in official, academic, and media texts to indicate regional scope. Examples include regionaaliset tiedot (regional data), regionaaliset erot (regional disparities), and regionaaliset kehitysohjelmat (regional development programs). It is frequently used alongside alueellinen to emphasize geographic scope, with the choice often depending on the preferred register or stylistic conventions.

Regionaaliset often appears in contexts related to administration, planning, and research. In statistical reporting or policy documents, data and analyses may be organized or labeled by region using this term to mark geographic differentiation. The noun-like use of the form is less common but can appear in lists or headings where multiple regional items are discussed.
