insatiable

Definitions

in- ('not') + sati (from satiare, 'to fill/glut') + -able ('able to be') = 'not able to be filled.' Where satiate means to fill a hunger completely, insatiable describes a hunger that can never be filled — appetite, greed, or curiosity that always outruns whatever it is fed.

Why It Means This

Insatiable almost always pairs with appetites and drives: an insatiable appetite, insatiable greed, an insatiable thirst for knowledge. The word carries a faint moral edge — it suggests wanting that has tipped past healthy 'enough' into something that can never be content.
