What does insatiable mean?
Insatiable describes a desire, appetite, or demand that cannot be satisfied or easily restrained. It may refer to physical needs, such as hunger or thirst, but it is also used figuratively for relentless curiosity, ambition, envy, or a market's demand. The word often suggests that no amount of what has been received is enough, although it does not necessarily mean that the need is literally endless. In business and economic contexts, “insatiable demand” indicates demand that persistently exceeds available supply. Because the term carries a strong, vivid implication, it is especially effective in literary and persuasive writing. It is related etymologically to satiate and satiety, words that describe fulfilling or being fully satisfied.

Where does insatiable come from?
Insatiable is formed from the Latin prefix in-, meaning “not,” and satiable, meaning “capable of being satisfied.” The latter comes from Latin satiare, “to satisfy,” ultimately related to satus, meaning “sated” or “sufficient.” The English word entered use in the 17th century in the sense of “not capable of being satisfied or glutted.”
