Chuck

Chuck is an English familiar name that developed as a pet form of Charles, itself derived from the Germanic name Karl, rooted in the Old High German element karal, meaning man or free man. The nickname likely evolved through the intermediate form Chick, with the sounds shifting naturally in colloquial American and British speech. It gained widespread use as an independent given name in the United States during the twentieth century, boosted by figures such as aviator Chuck Yeager and musician Chuck Berry. Related forms include Charles, Charlie, Carl, and Karl.
