Share-alike Share-alike (SA) Licensees may distribute derivative works only under a license identical to ("not more restrictive than") the license that governs the original work. (See also copyleft.) Without share-alike, derivative works might be sublicensed with compatible but more restrictive license clauses, e.g. CC BY to CC BY-NC.)
Non-commercial Non-commercial (NC) Licensees may copy, distribute, display, and perform the work and make derivative works and remixes based on it only for non-commercial purposes.
Non-derivative No Derivative Works (ND) Licensees may copy, distribute, display and perform only verbatim copies of the work, not derivative works and remixes based on it. Since version 4.0, derivative works are allowed but must not be shared.
