The story
- Proto-Indo-European · derived from*wer-
- Ancient Greek · derived fromὅρᾱμᾰ“sight”, “spectacle”
- English today-orama
Back-formation from panorama and cyclorama (which are modern coinages, not Greek words), and thus from Ancient Greek ὅρᾱμᾰ (hórāmă, “sight”, “spectacle”), in turn evolved from the Proto-Indo-European *wer-, meaning to perceive or look out for.
