Copyleft is a concept in copyright law that is used to ensure that a derivative work created from a copyrighted work remains as free as the original. It is a form of licensing that allows for the redistribution and modification of creative works, but with the stipulation that any subsequent versions of the work must also be licensed under the same or a compatible copyleft license. This contrasts with traditional copyright, which generally restricts the ability to copy, distribute, and modify a work.

The core idea behind copyleft is to promote the sharing and evolution of creative content. By requiring derivative works to also be freely available, copyleft licenses prevent proprietary restrictions from being imposed on works that were originally shared openly. This fosters a collaborative environment where knowledge and creativity can be built upon and disseminated without fear of legal repercussions.

Prominent examples of copyleft licenses include the GNU General Public License (GPL) for software and the Creative Commons ShareAlike license for creative works. These licenses ensure that the freedoms granted by the original author are preserved for all subsequent users and developers. While copyleft is often associated with open-source software, its principles can be applied to a wide range of creative content, including text, music, and art. The effectiveness of copyleft relies on the legal framework of copyright, which grants creators exclusive rights that they can then choose to waive or modify through licensing.
