A shape or structure that is half of a circle, often used in architecture or design.

Hemicycle → It is formed from "hemi-" (from Greek "hēmi-", meaning half) and "kyklos" (from Greek, meaning circle). The word "hemicycle" refers to a half-circle or a semicircular shape.
Think of 'half' ('hemi-') of a 'circle' ('kyklos') — that's why a hemicycle is a half-circle.
