After looking in the web I found this ref:-

//en.wikipedia.org/wiki/Cliché

And I was about to say what I thought it was; I refer to my mother's verses where the word silvern is repeatedly used, it might have some import in a poem in the Romantic period, but now appears totally fay (my own definition of fey); but why? Styles of writing change, and who are we to judge the poetry of another era when perhaps the word was used well, and didn't appear odd or cliché.

Consequently when I found myself using a completely legitimate word describing velvet, I felt the same twinge of discomfort with the word sheen, as I had with my mother's silvern, as if they were in another category that didn't have anything to do with good or original poetry.

Dictionary definition:
A phrase or opinion that is overused and betrays a lack of original thought.
A very predictable or unoriginal thing or person.
A stereotype or electrotype.

Electrotype: produces an exact facsimile of any object having an irregular surface, whether it be an engraved steel or copper plate, a wood-cut, or a form of set up type, to be used for printing...

So there's the thing. What do you think?
