Calle

Calle is a Swedish masculine name functioning as a familiar diminutive of Karl, which derives from the Old Germanic element karl, meaning man or free man. The root is shared across much of Europe and underlies numerous royal and historical figures, most notably Charlemagne, whose Latin name Carolus spread the name widely throughout the medieval world. In Scandinavia, Calle remains a popular pet form used both informally and as a given name in its own right. Related forms include Karl, Carl, Charles, and Carlo.
