License

The verb license or grant licence means to give permission. The noun license (American English) or licence (Indian English, British English, Canadian English, Australian English) refers to that permission as well as to the document recording that permission.

A license may be granted by a party ("licensor") to another party ("licensee") as an element of an agreement between those parties. A shorthand definition of a license is "an authorization (by the licensor) to use the licensed material (by the licensee)."

In particular a license may be issued by authorities, to allow an activity that would otherwise be forbidden. It may require paying a fee and/or proving a capability. The requirement may also serve to keep the authorities informed on a type of activity, and to give them the opportunity to set conditions and limitations.
