Cliche

A cliché or cliche (/ˈkliːʃeɪ/ or /klɪˈʃeɪ/) is an expression, idea, or element of an artistic work which has become overused to the point of losing its original meaning or effect, even to the point of being trite or irritating, especially when at some earlier time it was considered meaningful or novel.

In phraseology, the term has taken on a more technical meaning, referring to an expression imposed by conventionalized linguistic usage. The term is frequently used in modern culture for an action or idea that is expected or predictable, based on a prior event. Typically pejorative, "clichés" may or may not be true. Some are stereotypes, but some are simply truisms and facts. Clichés often are employed for comic effect, typically in fiction.

Most phrases now considered clichéd originally were regarded as striking, but have lost their force through overuse. The French poet Gérard de Nerval once said, "The first man who compared woman to a rose was a poet, the second, an imbecile."

A cliché is often a vivid depiction of an abstraction that relies upon analogy or exaggeration for effect, often drawn from everyday experience. Used sparingly, it may succeed, but the use of a cliché in writing, speech, or argument is generally considered a mark of inexperience or a lack of originality.

The word cliché is drawn from the French language. In printing, "cliché" came to mean a stereotype, electrotype or cast plate or block reproducing words or images that would be used repeatedly; the word seems to have derived from the clicking sound made when blocks were polytyped (a particular form of stereotyping in which the block was impressed into a bath of molten type-metal to form a matrix). Through this onomatopoeia, "cliché" came to mean a ready-made, oft-repeated phrase.
