perifereisten

Perifereisten is a Finnish grammatical form rather than a standalone concept. It is the genitive plural form of the adjective perifeerinen, meaning peripheral or relating to the outer edge of a system. In Finnish, adjectives agree with the noun they modify in number and case, and when describing a plural noun in the genitive, the adjective takes the form perifeeristen.

The form is commonly used in scientific, medical, geographic, and technical writing. For example, perifeeristen alueiden kehitys means “the development of the peripheral areas,” and perifeeristen hermosäikeiden toiminta means “the function of peripheral nerve fibers.” Other usages include perifeeristen verisuonten rakenteet, “the structures of peripheral blood vessels.” In such phrases, perifeeristen accompanies a noun in the genitive plural, producing a possessional or attributive sense over a larger whole.

Etymology and scope: perifeerinen is cognate with English peripheral and derives from international scientific vocabulary, with Finnish morphology adapting the form to match case and number. The genitive plural ending -en marks perifeeristen as the modifier for a plural noun in genitive. The nominative plural of the adjective is perifeeriset, which would appear before a plural noun in the nominative (e.g., perifeeriset alueet).

Notes: Perifereisten is not a separate term or concept; it is a grammatical form used to describe things that belong to or relate to the periphery within Finnish syntax. It is most at home in descriptive, analytical, or technical prose. See also perifeerinen and peripheral.
