Satiety comes from Middle French satieté, from Latin satietas ('sufficiency, fullness'), from satis ('enough'). The historical chain includes Latin satietas and Latin satis. Older glosses in the chain include "sufficiency, fullness" and "enough", which help explain the semantic range of the modern word. Morphologically, satiety is best read as borrowing, yielding an English noun shaped by both form history and later usage. In current English it functions as a noun, with the sense "the feeling of fullness or gratification beyond which desire ceases". related forms include satiate, sate, and satisfy. The result is an English noun whose etymology preserves the older forms while supporting the word's specialized modern meaning.
