Sferikos

Sferikos is the transliteration of the Greek adjective σφαιρικός, meaning spherical or globe-shaped. In modern Greek, it describes anything related to or shaped like a sphere and agrees in gender and number (σφαιρικός, σφαιρική, σφαιρικό). The root derives from Ancient Greek σφαῖρα (sphere, ball) with the adjectival suffix -ικός.

In scientific and mathematical terminology, sferikos is used to form compound terms for spherical concepts: σφαιρική γεωμετρία (spherical geometry), σφαιρικές συντεταγμένες (spherical coordinates), σφαιρικές αρμονικές (spherical harmonics). It also appears in descriptions of surfaces or bodies that are close to or exactly spherical, such as σφαιρικές επιφάνειες and σφαίρες in older texts.

In Greek-language texts, sferikos functions similarly to the English term spherical: it is used to denote properties, models, or measurements tied to a sphere. The word also appears in educational contexts when teaching geometry, astronomy, and physical sciences. Outside Greek, the English cognate is spherical, and the Latin-derived form sphaeric or sphaerical appears in some technical discussions.
