A slogan is a memorable motto or phrase used in a political, commercial, religious and other context as a repetitive expression of an idea or purpose. Slogans vary from the written and the visual to the chanted and the vulgar. Often their simple rhetorical nature leaves little room for detail, and as such they serve perhaps more as a social expression of unified purpose, rather than a projection for an intended audience.A message in its most general meaning is an object of communication. It is something which provides information; it can also be this information itself. Therefore, its meaning is dependent upon the context in which it is used; the term may apply to both the information and its form.
