Meaning

The etymology of the name comes from the common Germanic noun “*karlaz” meaning “free man,” which survives in English as “churl,” Old English (Anglo-Saxon) “ċeorl,” which developed its deprecating sense in the Middle English period. In turn, this name derives from the West Frankish name “Háriolus,” a pet form of Germanic names beginning with “*harjaz / *charja-,” meaning “army, army leader, commander, warrior.” The name took a Romanic influence. The Germanic “H” would be represented by a “C” in Romanic spelling; this is where the “C” or “K” came in. The feminine form Caroline and Carolina derive from “Carolus” which is Latin for Charles (English), from which it also derives Charlotte and its derivates. The name was brought in particular by Charlemagne “Charles the Great” and was at the time Latinized as Karolus as “in Vita Karoli Magni,” later also as Carolus. Charles the Great (German: Karl der Große; Latin: Carolus or Karolus Magnus) or Charles I, was the King of the Franks from 768, the King of Italy from 774, the first Holy Roman Emperor, and the first emperor in western Europe since the collapse of the Western Roman Empire three centuries earlier.
