Meaning & History
Kati is a feminine given name used in Finland, Estonia, and Hungary. In Finnish and Estonian, it serves as a diminutive of Katariina, while in Hungarian it is a diminutive of Katalin.

The Estonian diminutive Kai is also related. Modern forms in other languages such as Russian Katerina, Ukrainian Karyna, and Belarusian Katsiaryna share the same ultimate root.
The parent name Katherine has a long history, famously associated with Saint Catherine of Alexandria, a 4th-century martyr who was tortured on a wheel. The name was introduced to Western Europe by crusaders and has been common in England since the 12th century. Notable historical bearers include Catherine of Siena, Catherine de' Medici, and several queens and empresses. Despite Kati being a relatively informal variant, it is a recognized given name in its own right across the Baltic and central European region.
