Etymology: Ancient Greek "opsis" meant "sight" or "appearance," and it comes from the verb "optesthai," "to see" in the future tense, a form of the root "ops," "eye" or "face." The same root gave English a large family of words, including "optic," "optical," and "optics." In classical Greek drama, "opsis" was the term for the visual spectacle of a performance: the costumes, scenery, masks, and staging, as opposed to the words of the play. Ancient critics such as Aristotle listed it as one of the elements of tragedy, and they treated it as the least essential of them, something the poet did not need to rely on. The word passed into English mainly through scholarly and technical writing, where it is used in the sense of a visual aspect or appearance. Because it survives mostly in learned contexts, it is rarely heard in everyday speech, though its relatives are familiar.
