peripheren

Peripheren is not a standalone concept in English. In German-language technical writing, peripheren is the weak inflected form of the adjective peripher (peripheral) used before plural nouns or definite phrases to denote something located at the edge or boundary of a system. In English, corresponding terms are peripheral or periphery.

In science and medicine, the root concept refers to structures away from the center: the peripheral nervous system, peripheral blood, peripheral nerves, and peripheral organs. In biology and medicine, the term is often contrasted with the central nervous system (CNS). In geography and economics, peripheral regions describe areas at the edge of a country or economic core, frequently contrasted with core regions.

In computing and information technology, peripheral devices (such as printers, scanners, and external drives) are hardware connected to a computer but not part of its core processor. In geometry, the periphery denotes the boundary or circumference of a shape; for a circle, the circumference is its periphery.

Linguistically, peripheren functions as an inflected adjective in German and other Germanic languages; it does not stand alone as a common noun. See also peripheral, periphery, peripheral nervous system.
