What literary term is used for an overused phrase or idea?

A cliché refers to an expression, idea, or phrase that has become overly familiar and predictable due to its frequent use. Clichés often lose their original impact and freshness, making them less effective in conveying meaning or emotional resonance. In literature, writers aim to avoid clichés in order to create more original and engaging work, as these tired expressions can detract from the creativity and uniqueness of their writing.

Novelty, on the other hand, implies something new and original, which is the opposite of a cliché. Symbolism is a literary device where symbols are used to represent ideas or qualities, while a motif is a recurring element that has significance in a literary work. Both of these terms carry different connotations and are not synonymous with the idea of an overused phrase or concept.
