Kaj

1. Kaj name meaning and origin

The name Kaj is of Scandinavian origin, primarily used in Denmark and Sweden. It is derived from the Latin name Caius or Gaius, which was a common Roman praenomen (personal name) meaning 'rejoice' or 'happy'. In Nordic countries, Kaj has been a popular masculine given name since the early 20th century, representing strength and northern heritage.

The Danish and Swedish variant Kaj (sometimes spelled Kay in English contexts) gained wider recognition through Hans Christian Andersen's fairy tale 'The Snow Queen' (1844), where Kay is one of the main characters. This literary connection helped spread awareness of the name beyond Scandinavia, though it remains most common in Nordic countries. The name's brevity and distinctive pronunciation have contributed to its enduring appeal across generations.

2. Kaj name popularity

Kaj is a masculine name with Scandinavian origins, though it has spread to English-speaking countries including the United States and United Kingdom. The name derives from the Danish and Norwegian variant of Kai, which itself comes from the Old Norse name Kái, meaning "rejoice" or possibly connected to the Frisian word for "warrior."

Despite its distinctive sound and international character, Kaj remains relatively uncommon in both the US and UK. It hasn't ranked among the top names in either country in recent years, making it a unique choice for parents seeking something with Nordic heritage that stands out from more popular Scandinavian imports like Erik or Sven.
