peripherikos

Peripherikos is a term drawn from Modern Greek, generally rendered in English as peripheral or regional. In Greek itself, the adjective περιφερικός (translit. peripherikós or peripherikos) describes something that lies at the edge or outer part of something, or that relates to a region or periphery. The feminine and neuter forms are περιφερική and περιφερικό, respectively, and the term participates in compound phrases such as περιφερειακός, which conveys a sense of regional scope or peripheral character.

Etymology and forms

The word is built from the prefix péri, meaning around or about, combined with a root that conveys bearing or relation to a boundary, and the standard Greek adjectival suffix -ikos. This yields meanings centered on edge, boundary, or outward extent. In practice, περιφερικός is used across disciplines to signal peripheral position or regional affiliation. The related noun περιφέρεια denotes a region or administrative periphery, while περιφερειακός describes devices, structures, or concepts tied to the periphery rather than the center.

Usage

In science and medicine, περιφερικός refers to peripheral structures, for example περιφερειακό νεύρο (peripheral nerve) or περιφερειακή κυκλοφορία (peripheral circulation). In technology and computing, περιφερειακός εξοπλισμός or περιφερειακές συσκευές means peripheral devices. In administration, περιφερειακός can describe regional or peripheral units within a larger national framework.
