Perifeerisistä

Perifeerisistä is the elative plural form of the Finnish adjective perifeerinen, meaning peripheral. The term is used to describe things that originate from, relate to, or come from the periphery or outer parts of a structure, system, or field. In scientific and medical Finnish, perifeerinen is a common label for locations or aspects situated away from a central or core area.

In Finnish, adjectives of the -inen class decline for case and number. For perifeerinen, the elative plural form is perifeerisistä, used with plural nouns in the elative case. Examples include “perifeerisistä kudoksista” (from peripheral tissues) and “perifeerisistä hermopäätteistä johtuvat oireet” (symptoms arising from peripheral nerve endings). The corresponding nominative plural is “perifeeriset,” while the genitive plural is “perifeeristen.”

Etymology reflects the concept of the periphery. The Finnish term perifeerinen derives from perifeeri, itself linked to the Greek roots peri- ‘around’ and pherein ‘to bear,’ adapted into Finnish medical and scientific vocabulary through broad European linguistic influence.

Usage and scope: The form perifeerisistä appears mainly in scientific, medical, or technical Finnish. It is used to refer to peripheral tissues, nerves, or phenomena located at the body's edge, as well as to discuss peripheral aspects of a topic (for example, peripheral observations or peripheral concerns) in scholarly writing.
