platitude
cliché / banality / truism
Noun
pl: platitudes
This term describes a statement that is technically true but has lost its impact through overuse. It carries a strong negative connotation of insincerity or intellectual laziness, suggesting that the speaker is relying on a cliché to avoid engaging in a meaningful or original conversation. In professional or political contexts, it often refers to vague promises or moralizing slogans that sound impressive but lack substance. It differs from a simple cliché in that it specifically targets statements intended to appear profound or wise.
