Learnalism was a serendipitous typo that stuck! For a more in depth definition, visit the  “What Is Learnalism Page”

Copyleft is a form of licensing and can be used to maintain copyright conditions for works such as computer software, documents, music and art. In general, copyright law is used by an author to prohibit others from reproducing, adapting, or distributing copies of the author's work. In contrast, an author may give every person who receives a copy of a work permission to reproduce, adapt or distribute it and require that any resulting copies or adaptations are also bound by the same licensing agreement. Copyleft type licenses are a novel use of existing copyright law to ensure a work remains freely available. The GNU General Public License, originally written by Richard Stallman, was the first copyleft license to see extensive use, and continues to dominate the licensing of copylefted software. Creative Commons, a non-profit organization founded by Lawrence Lessig, provides a similar license called ShareAlike.

So says Wikipedia.
