Grassa

Grassa is the feminine singular form of the Italian adjective grasso, meaning fat, thick, or greasy depending on context. It agrees with feminine singular nouns; the masculine form is grasso, the feminine plural is grasse, and the masculine plural is grassi. The term derives from Latin crassus and is cognate with related Romance-language words describing thickness or fatness.

In Italian usage, grassa modifies nouns to indicate substantial fat content or density. For example, una persona grassa means a fat person, una crema grassa can describe a fatty cream, and piante grasse refers to succulent plants—the latter is a common horticultural term. The adjective is used as a standard descriptive descriptor across contexts.

Grassa also occurs as a surname in Italy. As a family name, it is of Italian origin and is borne by individuals in various regions. It is less common than grasso or grassi but is attested in genealogical and contemporary records. Related forms include grasso (masculine singular) and grasse (feminine plural).
