phantasmagorical

The word's journey begins with the Greek phantasma, meaning "apparition" or "illusion," itself derived from the verb phainein, "to show." This root passed into Latin and later French before entering English. The second element, agora, originally denoted a public gathering place in ancient Greek cities. In the late 18th century, the French coined phantasmagorie for a magic lantern show producing rapidly changing, spectral images, metaphorically a "gathering of phantoms." The English adjective phantasmagorical was formed by adding the suffix -ical to this noun, shifting the sense from a specific spectacle to the general quality of being wildly shifting, unreal, and dreamlike. Thus, the literal logic of a "gathering of illusions" evolved into the modern abstract meaning describing anything with a bizarre, deceptive, and fantastical quality.
