What is the term for the origin of a cliche?

From wiki sources :

A cliche 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.

Consider (for example) a sentence framed by Shakespeare

"A rose by any other name would smell as sweet"

which became very popular. Now-a-days, it may be overused or irritating and hence may be considered a cliche, but Shakespeare himself did not use it as a cliche.

What did he use it as ? What did he invent ? What is the term for the origin of a cliche ?

Solution 1:

Archetype:

1.1 An original which has been imitated; a prototype:
ODO

Prototype:

1.1 The first, original, or typical form of something; an archetype:
ODO

Original!

Solution 2:

In speech or writing, a future cliché begins as a turn of phrase, which Merriam-Webster's Eleventh Collegiate Dictionary (2003) defines as

a fashioning of language or arrangement of words : manner of expression

Solution 3:

The best I can think of is first use or original use. After all, when an "expression, idea, or element of an artistic work" is first used, it cannot be a cliché. It only gains the description when it becomes so popular as to be overused.

Solution 4:

With regard to the question about how cliches are first created, the first thing that popped into my head when I read this question was "Coin a phrase". This article even cites The Bard of Avon in several places. I fully expected someone else had already answered with it.

This paragraph seems to capture the idea of newly created phrases or words nicely:

From there, the verb “to coin” started to refer to anything that was made into something new. By the sixteenth century, coining new words became quite popular, though it wasn’t always considered a positive, innovative thing. In 1589, George Puttenham wrote in The Arte of English Poesie: “Young schollers not halfe well studied… will seeme to coigne fine wordes out of the Latin.”

Regarding the word cliché:

Printing presses gave us the word “cliché,” which comes from the French word cliquer, which referred to the clicking sound made by the stamps on the metal typefaces during printing. How did this come to mean “a phrase or opinion that is overused and betrays a lack of original thought?” Printer’s used “cliché” as jargon for “stereotype block.” From there, the evolution of the meaning of the word followed closely with “stereotype,” the latter of which was originally a “method of printing from a plate,” from the French “stéréotype” in the eighteenth century. By the mid-nineteenth century, this had come to mean “image perpetuated without change.” This further morphed by the early twentieth century to mean as it does today.

Solution 5:

The classic exemplar can become trite when familiarity breeds contempt:

classic

adjective

1 Judged over a period of time to be of the highest quality and outstanding of its kind:

exemplar

noun

A person or thing serving as a typical example or appropriate model:

ODO

An ideal form captures an archetypical sentiment, but the external paradigm can wear thin until it ceases to capture the imagination. I dare say that the fine expression posited as an example has not reached this sorry state.
