Charlie

Charlie is an English diminutive and pet form of Charles, which derives from the Germanic name Karl, rooted in a word meaning man or free man. The name gained widespread use through the enduring popularity of Charles across European royalty and nobility, most famously Charlemagne, the medieval Frankish emperor whose Latin name combined Carolus with Magnus. Originally used informally for males, Charlie has grown into an independent given name used for both boys and girls in modern times. Related forms include Charles, Carl, Karl, and the feminine Charlotte and Carlotta.
