Overview
Gustavus is the Latinised form of the male given name Gustav or Gustaf, of likely Old Swedish origin, used mainly in Scandinavian countries, German-speaking countries, and the Low Countries, possibly meaning "staff of the Geats or Goths or gods", possibly derived from the Old Norse elements ("Geats"), / ("Goths") or ("gods"), and ("staff"). Another etymology speculates that the name may be of Medieval Slavic origin, from the name Gostislav, a compound word for "glorious guest", from the Medieval Slavic words ("guest") and ("glory") and was adopted by migrating groups north and west into Germany and Scandinavia. This name has been borne by eight Kings of Sweden, including the 16th-century Gustav Vasa and the current king, Carl XVI Gustaf. It is a common name for Swedish monarchs since the reign of Gustav Vasa. The name has entered other languages as well. In French it is ; in Italian, Portuguese and Spanish it is Gustavo.
