avidity

This term describes a hunger for acquisition or achievement that borders on the obsessive. It carries a stronger, more urgent energy than simple interest or enthusiasm, often suggesting a predatory or consuming quality. While it can be used positively to describe a passion for learning, it frequently leans toward a connotation of greed or an insatiable appetite.

As an uncountable noun, avidity cannot be pluralized or counted with numbers. To quantify this quality, speakers must use partitive constructions such as a degree of avidity or a certain level of avidity.
