Copyleft

Copyleft works can be shared both in original form and after being adapted, but they must remain under the copyleft licence even if they are modified.

Copyleft licences are also called 'reciprocal', 'viral' and 'share alike' libre licences. However, whereas copyleft can only describe a libre work, the other three terms can also describe proprietary works that must be kept under the same (proprietary) licence when adapted.
