Gustav (name)
Gustav, also spelled Gustaf, is a male given name of Old Swedish origin, used mainly in Scandinavian countries, German-speaking countries, and the Low Countries. The origin of the name is debated. The name was first recorded in 1225 in Västergötland, Sweden, in the Latin form Gostauus. Other 13th-century variants include Gødstaui, Gøstaf and Gøzstaf. Linguist Otto von Friesen suggested that it may derive from a byname meaning "staff of the Göta people" or "support of the (Väst)göta people". Another theory speculates that the name is of Medieval Slavic origin, from Gostislav, a compound word meaning "glorious guest", derived from the Slavic words gostь ("guest") and slava ("glory"), and was adopted by migrating groups north and west into Germany and Scandinavia.
