Synonym discussion

Sense: noun/3

Fullness, satiety, and repletion all describe the feeling of having eaten enough, but they differ in register and nuance. Fullness is the everyday, neutral word: you might tell a friend 'I love the fullness I feel after a bowl of noodles.' Satiety is more formal and scientific, common in nutrition and biology contexts — a researcher might say 'this hormone signals satiety to the brain.' Repletion is the rarest of the three, with a formal or even literary tone, often implying one has eaten to the point of abundance or even excess. In casual conversation, 'fullness' is the most natural choice. In an academic article about appetite control, 'satiety' is preferred. Use 'repletion' only for stylistic effect in formal writing.

Etymology

Proto-Indo-EuropeanProto-GermanicOld EnglishEnglish

Fullness comes from Old English 'fullnes' (or 'fyllnes'), a combination of 'full' (meaning full, filled) and the suffix '-nes' (-ness), which turns adjectives into nouns that mean 'the state or quality of being.' The word has been in English since before the 12th century, making it one of the older abstract nouns in the language. Its Germanic root goes back to Proto-Germanic *fullaz (full) and *-inassu- (-ness), and further to the Proto-Indo-European root *pleh₁- (to fill), which also gave English 'fill,' 'plenty,' and 'plural.'
