What does 'hackneyed' imply about an idea or expression?

The term 'hackneyed' refers to something that has become stale or unoriginal due to overuse. When an idea or expression is considered hackneyed, it implies that it has been repeated too often, leading to a loss of its original impact or effectiveness. This is often used in contexts where creativity is valued, as hackneyed phrases or concepts are seen as clichéd or lacking novelty. This understanding highlights the negative connotation associated with the term, as it denotes a deficiency in originality and freshness. Thus, the correct implication of 'hackneyed' aligns perfectly with the idea of something that has been overly relied upon to the point of triviality.
