Etymology
The word "insatiable" originates from the Latin insatiabilis, which is itself a combination of the negative prefix in- and the adjective satiabilis, meaning "that can be satisfied." Satiabilis derives from the verb satiare, "to satisfy," and the root satis, meaning "enough." This root, satis, is traced back to the Proto-Indo-European root seh₂-, meaning "to satisfy." Thus, the literal construction "not capable of being made enough" has evolved seamlessly into the modern abstract meaning describing an appetite, desire, or curiosity that cannot be fulfilled.
