What does fattier mean?
Fattier is the comparative form of the English adjective 'fatty', used to indicate that one thing contains more fat than another. It belongs almost entirely to the domain of food and nutrition: cooks compare fattier cuts of meat, dietitians weigh fattier dairy options, and health writers contrast fattier fish with leaner ones. Grammatically, it functions like other short comparatives — formed by adding '-ier' rather than using 'more' — so one says 'fattier meat', never 'more fattier'. Because it expresses relative rather than absolute fatness, it typically pairs two items in a comparison. Its connotations shift with context: in dietary advice it often carries a cautionary tone, since higher-fat foods are frequently linked with higher calories, while in culinary writing richness from fat is prized for flavor and texture. Simple, transparent, and widely understood, 'fattier' is a practical word for anyone navigating menus, recipes, or nutrition labels.

Etymology of fattier
'Fattier' derives from 'fatty', formed by adding the adjectival suffix '-y' to the Old English noun 'faett' (modern 'fat'), which is common Germanic and cognate with words such as German 'fett' and Dutch 'vet'. The comparative '-ier' follows the standard English pattern for adjectives ending in '-y', which lose the 'y' and take '-ier' (as in 'happy' → 'happier'). Its earliest uses thus trace back through Middle English to Old English roots shared across the Germanic language family.
