Karlie is associated with the meaning “Free woman, strong and womanly” — a beautiful sentiment to see brought to life in your child’s room.
Karlie is a modern feminine variation of the name Karl, which comes from the Old Germanic word "karl," meaning "free man" or "strong man." Karl itself is the Germanic form of Charles. The "ie" ending transforms a traditionally masculine root into a softer, feminine form that became popular in English-speaking countries during the 20th century.
