Pernicious

Definition

Meaning

"Pernicious" is an adjective that signifies something extremely harmful, destructive, or detrimental. It describes a quality or influence that has a pervasive, damaging impact, often hidden or gradual in its onset. Pernicious forces can undermine health, morality, or well-being. It implies a subtle and insidious nature, as opposed to something overtly dangerous. For example, pernicious habits may slowly erode one's physical or mental health over time. In a broader context, pernicious ideologies can have far-reaching and negative consequences on societies and cultures. Recognizing pernicious elements is vital to mitigate their harm, as they can be masked by superficially positive qualities. Vigilance and proactive measures are necessary to counteract pernicious influences, whether in personal life, public discourse, or broader societal issues.
