Up until now the maning of CLICHE has always been knwn to me in certain fashion without me really knowing the textbook meaning.
According to the Free--Online--Dictionary.
{quote]
cli·ché also cliche (kl-sh)
n.
1. A trite or overused expression or idea: "Even while the phrase was degenerating to cliché in ordinary public use . . . scholars were giving it increasing attention" (Anthony Brandt).
2. A person or character whose behavior is predictable or superficial: "There is a young explorer . . . who turns out not to be quite the cliche expected" (John Crowley).
--------------------------------------------------------------------------------
[French, past participle of clicher, to stereotype (imitative of the sound made when the matrix is dropped into molten metal to make a stereotype plate).]
Synonyms: cliché, bromide, commonplace, platitude, truism
These nouns denote an expression or idea that has lost its originality or force through overuse: a short story weakened by clichés; the old bromide that we are what we eat; uttered the commonplace "welcome aboard"; a eulogy full of platitudes; a once-original thought that has become a truism.[/quote]
Like I've always known it's a CLICHED idea that the herioc knight will befreind a monster that turns out to be good. If you've read Dragonalnce Kaz the Minotaur
While my intepretion isn't altogther wrong it's just shouldn' be thought as something that can be so common and that get overused it loses it's power.
