Explanation

The term "clichÊ" refers specifically to expressions, phrases, or ideas that have become so overused that they have lost their original impact or novelty. This linguistic redundancy often stems from their frequent use in literature, conversation, or culture. When a phrase is repeatedly employed, it can become predictable and uninspired, making it less effective at conveying its intended message.

For example, phrases like "think outside the box" or "at the end of the day" started as fresh ideas but have since evolved into clichÊs due to their rampant usage. As a result, they can annoy or disengage audiences, failing to evoke the intended emotional response.

In literary contexts, clichÊs can hinder the depth and originality of writing. Writers are often encouraged to avoid clichÊs in favor of more inventive language to keep their work engaging and impactful. Thus, the correct answer to the question is D: "An overused expression," as it accurately encapsulates the essence of what a clichÊ truly represents in communication.
