* The constant flow of language: New phrases become popular and then overused, solidifying their place as clichés.
* Culture and time: Clichés often reflect trends, societal norms, and popular culture, changing as these things do.
* Subjectivity: What one person considers a cliché, another might find fresh and engaging.
Instead of focusing on an exact number, it's more useful to understand the concept of a cliché: an overused phrase or expression that has lost its originality and impact.
So, there are likely thousands, if not millions of clichés out there, and new ones emerge all the time!
