fattier

Fattier is the comparative form of the adjective fat in English. It is used to describe a greater amount of fat, or a higher fat content, in one item relative to another. Both fattier and fatter are recognized as the comparative forms of fat, but fattier is less common and often chosen to emphasize fat content or to fit a particular stylistic tone.

In nutrition and cooking, fattier foods contain more fat than leaner equivalents. The term appears in product comparisons and descriptions, for example describing dairy, meats, or oils as fattier than alternatives. It is typically used to highlight differences in fat content rather than to comment on health or body size.

When describing people or living beings, fatter is the more common choice. Fattier tends to be reserved for contexts focusing on fat content in foods or in stylistic variations rather than routine descriptions of weight or physique. As with all comparative adjectives, tone and context influence acceptability, and more neutral terms may be preferred in sensitive discussion.

Etymologically, fattier is formed from fat by adding the comparative suffix -ier, alongside the more standard -er form. It is attested in English usage, especially in culinary or nutritional discourse, where it helps to convey a higher proportion of fat in comparison to a reference item.
