Orthoscopic → It is formed from "ortho-" (from Greek "orthos", meaning straight or correct) and "scopic" (from Greek "skopein", meaning to look or to examine). The word "orthoscopic" refers to an instrument or method that provides a correct or straight view, particularly in optics.
Think of 'straight' ('ortho-') and 'looking' ('scopic') to remember that 'orthoscopic' means providing a correct view.
