Dastardise is a term derived from the word "dastard." It is a verb that is used to describe the action of making someone or something cowardly, lowly, or base. The term is often used in a figurative sense to convey the act of reducing someone or something to a deplorable or despicable state. Dastardise implies the degradation of one's character, integrity, or reputation, resulting in a loss of respect or trust from others.
When someone or something is dastardised, it suggests a deliberate act of diminishing their noble qualities or honorable traits. This could manifest as undermining someone's courage, bravery, or loyalty, turning them into a timid or treacherous individual. Similarly, dastardising an object or idea involves tarnishing its positive attributes, making it appear untrustworthy, dishonest, or unworthy of admiration.
The term can also be used in a broader context, beyond referring to a specific person or concept. For example, one might say that a manipulative political campaign has dastardised the democratic process. This indicates a distortion of the system's original principles, resulting in the erosion of the public's trust and confidence in the institutions involved.
Overall, dastardise describes the act of degrading someone's character or tarnishing the reputation of something, transforming it into a lesser, more contemptible state.
To make cowardly.
