Where Insatiable Comes From
Parts of Speech: Adjective
Syllables: in-sa-ti-a-ble
Origin: Insatiable comes from Late Middle English insaciable, from Latin insatiābilis, meaning “not able to be satisfied.” It combines Latin in- (“not”) with satiābilis, from satiare (“to fill or satisfy”).
Prefix/Suffix Breakdown: in- = not + sati- = satisfy or fill + -able = capable of being.
The core idea has remained stable: something insatiable cannot be fully satisfied.
Insatiable: Meaning and Definition
The simplest definition for insatiable is:
Not able to be satisfied; always wanting or needing more.
Cambridge defines insatiable especially in relation to a desire or need that is too great to satisfy. Collins similarly describes someone with an insatiable desire as wanting as much as possible.
Examples include:
- an insatiable appetite for food
- an insatiable desire for success
- an insatiable thirst for knowledge
- an insatiable hunger for power
- an insatiable curiosity
- an insatiable demand for housing
These collocations are also reflected in current dictionary examples.

When NOT to Use Insatiable
Do not use insatiable simply to mean “very large,” “strong,” or “frequent.”
