About

"Free software" is a matter of liberty, not price. To understand the concept, you should think of "free" as in "free speech", not as in "free beer". Free software is a matter of the users' freedom to run, copy, distribute, study, change and improve the software. --[GNU Project]

Copyleft

Copyleft says that anyone who redistributes the software, with or without changes, must pass along the freedom to further copy and change it. Copyleft guarantees that every user has freedom. --[GNU Project]

Copyright

Copyright is a form of protection provided by the laws [...] to the authors of “original works of authorship”, including literary, dramatic, musical, artistic, and certain other intellectual works. --[U.S. Copyright Office]
