insatiable

What does "insatiable" mean?
The word "insatiable" describes an appetite, desire, or curiosity that is so intense it can never be fully satisfied. Imagine a bottomless pit or a fire that consumes everything in its path but only grows hungrier; it captures the essence of a hunger that persists no matter how much you feed it. It is most commonly used to describe abstract desires, such as an "insatiable thirst for knowledge" or an "insatiable ambition." While it can be used for literal hunger, it sounds quite dramatic in that context and is usually reserved for metaphorical or psychological cravings.
