Meaning & History
Gustaf is a Swedish variant of the name Gustav. It has been used historically in Sweden alongside the more common form Gustav, often appearing in royal and aristocratic contexts.
Etymology
The name shares the same debated etymology as Gustav. The most widely accepted theory traces it to the Old Norse elements gautr meaning "Geat" and stafr meaning "staff", interpreting the name as "staff of the Geats". However, the compound name Gautstafr is not securely attested in Old Norse records. Alternatively, the Slavic name Gostislav has been proposed as a source, though evidence is limited. The traditional Swedish usage of the -f ending in place of -v reflects an older orthographic convention.
History and Usage
In Sweden, Gustaf has been a traditional given name for centuries. According to Swedish statistical data from 2010, 43,816 males bear the name Gustaf, compared to 80,029 named Gustav, indicating its enduring but less frequent use. Its popularity peaked in the 1910s, and many bearers are now elderly. The name is strongly associated with Swedish royalty; six kings of Sweden have borne the name Gustav, including Gustav I Vasa (16th century), although the variant Gustaf was also used among the nobility.
Notable Bearers
While the most prominent historical figures carry the Gustav spelling, Gustaf has been borne by many notable Swedes, including 19th- and early 20th-century cultural figures such as the painter Gustaf Cederström. The name also appears in the surname Gustafsson, a patronymic meaning "son of Gustaf".
Variants and Related Forms
Related names include the Swedish diminutive Gösta, the variant Göstav, and the more standard Gustav. In other languages, the name appears as Gustaaf (Dutch), Kustaa (Finnish), and Kyösti (Finnish). The feminine form Gustava exists but is rare.
