What does fattiness mean?
Fattiness is the quality of containing or consisting largely of fat, most often applied to food. When cooks and food writers speak of the fattiness of a ribeye, a slice of pork belly, or a wedge of triple-cream brie, they are describing how much fat the item carries and how that fat registers on the palate — as succulence, unctuousness, or heaviness. The term is evaluative as well as descriptive: in some contexts fattiness is prized, since fat dissolves flavor compounds and delivers richness that lean ingredients cannot match, while in others it is criticized as greasy or unhealthy, which is why pairings like acidity, salt, or bitterness are said to 'cut through' fattiness. Beyond cuisine, the word can describe fatty tissue in biological or medical discussion. Derived simply from the adjective 'fatty' plus the common suffix '-ness', fattiness is an uncountable noun, used chiefly when a writer wants a precise, analytic way to talk about degree of fat rather than fatness of a person or animal.
nounThe quality or state of containing a large amount of fat; the degree to which something, especially food, is fatty or rich in fat.
- The quality of food or other substance of being high in fat content or richly fatty in texture and taste.
- More broadly, the property of any material or tissue consisting largely of fat.
"The cheesecake's luxurious fattiness is precisely what makes it so satisfying."
"A squeeze of lemon cuts beautifully through the fattiness of the salmon."
"The butcher explained that the steak's fine marbling promised just the right fattiness."
Rarely used; as an abstract quality noun, 'fattiness' is effectively uncountable, though a plural can technically occur when contrasting distinct instances of the quality.
"The tasting menu showcased the different fattinesses of five heritage-breed pigs."
Fat carries flavor — which is why chefs often praise a cut of meat not despite its fattiness but because of it.

Etymology of fattiness
Fattiness is formed within English from the adjective 'fatty' plus the productive suffix '-ness', which turns qualities into abstract nouns. The underlying word 'fat' descends from Old English 'fǣtt', meaning 'fatted, plump', which itself traces back to the Proto-Germanic verb *fatjan, meaning 'to make fat'. Cognates appear across the Germanic family, including Old Norse 'feitr' and German 'fett'. The suffixed form 'fattiness' arose as part of the regular English pattern of building quality nouns from adjectives, alongside words like 'thickness' and 'ripeness'.
How fattiness is actually used
Fattiness is an uncountable abstract noun describing a quality rather than a thing, so it almost never takes an article in ordinary use ('the fattiness', not 'a fattiness'). It appears most often in food writing, cooking, and nutrition contexts, where it is usually evaluative rather than neutral — fattiness may be celebrated as richness or criticized as grease depending on the dish and the writer's aims. It is far less common than the adjective 'fatty' and tends to signal a slightly more analytical or connoisseurial tone.
