• Etymology Today from M-W: satiety \suh-TYE-uh-tee\

1 : the quality or state of being fed or gratified to or beyond capacity : surfeit, fullness
2 : the revulsion or disgust caused by overindulgence or excess

You may have guessed that "satiety" is related to "satisfy," "satiate" (meaning "to satisfy fully or to excess"), or "sate" (which means "to glut" or "to satisfy to the full"). If so, you guessed right. "Satiety," along with the others, ultimately comes from the Latin word "satis," which means "enough." English speakers apparently couldn't get enough of "satis"-derived words in the 15th and 16th centuries, which is when all of these words entered the language. "Satiety" itself was borrowed into English in 1533 from the Middle French word "satieté" of the same meaning.
