Origin:English, diminutive of Charles
Description:Charlie derives, of course, from the classic name Charles which, in turn, comes from a German word meaning "free man." Charles became very popular in France during the Middle Ages due to the fame of Charles the Great, also known as Charlemagne. Charley is an alternate spelling.
Origin:Diminutive of Charles or Charlotte
Description:Charlie is one of the friendly, tomboyish male nickname names--another is Sam-- now used almost as frequently for girls: in 2015, it ranked higher on the girls list than on the boys list for the first time. That makes Charlie one of the most popular unisex names around today. The name Charlie, for females, has been jumping up the charts since it reappeared, after a 50-year hibernation, in 2005.
