Grosseiros

Grosseiros is a toponym used in Portuguese-language regions to denote a geographic locality. The name derives from the adjective grosseiro, meaning rough, coarse, or rustic, and historically described terrain, land use, or a community associated with such characteristics.

Geographic usage is typically at a local level rather than indicating a major town. In Portugal and other Portuguese-speaking areas, several small localities or subdivisions within municipalities may bear the name Grosseiros. Because such toponyms are often duplicated across regions, the term by itself does not identify a single, universally recognized place without additional geographic qualifiers such as municipality or district.

In historical and genealogical records, Grosseiros can appear as a placename component within parish, civil parish, or cadastral descriptions. When researching a specific Grosseiros, sources such as municipal archives, parish books, and historical maps can help distinguish which locality is intended.

Beyond geographic use, Grosseiros may also appear as a surname or element in personal names in Portuguese-speaking countries, though it is less common than the noun-based toponym.
