Karolina
Karolina is a feminine form of the name Carolus, which is the Latin form of Charles. The name Charles is derived from the Germanic name Karl, which means 'free man'.
The name Karolina has its roots in the Germanic and Frankish tribes of Europe, where the name Karl was common among rulers and nobility. The name gained widespread popularity after the reign of Charlemagne, the King of the Franks and the first ruler of the Holy Roman Empire.
In many Slavic and Eastern European languages, such as Polish, Czech, and Russian, the feminine form Karolina is more commonly used than the masculine form Karol or Karel. It is a popular name in these regions, as well as in other parts of Europe and the Americas.
While the name Karolina has a regal and historic feel, it is also considered a modern and stylish name, with various spelling variations like Carolina or Karoline adding a unique touch.
