Unlicense
Noun · Open Source
Definitions
A permissive software license intended to dedicate code to the public domain while also providing fallback license terms where pure public-domain dedication may not be recognized. It is used by projects seeking maximal simplicity and freedom of reuse.
In plain English: A software license meant to make code as close to public domain as practical.
Example: "They chose the Unlicense because they wanted the code to be as close to unrestricted reuse as possible."
