Gros is a French surname meaning "thick, fat, big" in French, derived from the Late Latin grossus meaning "large" or "thick", which may have Germanic origins. As a descriptive surname, it likely originated as a nickname for a large or stout person, a common practice across many cultures. Etymology and Distribution The root of the name is the Latin grossus, which gave rise to French gros and similar words in other Romance languages. The surname is predominantly found in France and other French-speaking regions, including parts of Belgium, Switzerland, and Canada. Variants include Grossi (Italian) and Grosso (also Italian), which share the same etymology but show the characteristic Italian alteration of the suffix.
