What does 'pervasive' indicate?

The term 'pervasive' describes something that is widespread or exists throughout a particular area or environment. When something is described as pervasive, it suggests that it is not confined to one specific location but is instead integral to many different parts or aspects. This characteristic reflects thoroughness and can often imply that the effect or presence of whatever is being described influences a broad scope.

For instance, one might say that a particular idea or trend is pervasive in a culture, meaning that it can be found everywhere within that social environment, affecting many people or elements simultaneously. This definition aligns perfectly with the answer chosen, as it captures the essence of something widespread in existence or influence.
