Wikipedia defines a cliché as an expression, idea, or element of an artistic work which has been overused to the point of losing it original meaning or effect, rendering it a stereotype, especially when at some earlier time it was considered meaningful or novel. The term is often used in modern culture for an action or idea which is expected or predictable, based upon an earlier event
We are becoming a society that is too dependent upon the use of clichés. As this dependency has grown we have relied less on the use of quotations as a way to communicate previously enunciated ideas. Who said it and when and why was it said seems to get lost in the rush to make a point.
If we are going to better get along with each other, we must relearn proper English. Each of us must communicate and debate ideas in precise and clear terms.
