The term PREVIEW can be defined as a SNEAK, FORETASTE, PEEK, or sneakpeek. A SNEAK is a quick, furtive look at something, while a FORETASTE is a small sample of something that gives an idea of what the full experience will be like. A PEEK is a brief, often surreptitious, look at something, and a sneakpeek is a secret preview of something before it is officially released. All of these terms refer to getting a glimpse of something before it is available to the public.
