Cyclorama is formed from "cyclo-" (from Greek "kyklos", meaning circle) and "orama" (from Greek "horama", meaning view or sight). The word describes a circular view or panoramic scene, typically seen in a large format.
Imagine a 'circle' ('cyclo-') that offers a 'view' ('orama') of a scene — that's what a cyclorama is, a circular panoramic view.
