A copyright is a legal concept that grants (negotiable) monopoly privileges to authors to duplicate, modify, and distribute physical forms of an abstract thing called a "work", which, at least in the United States, has to exhibit "originality", and must be a "specific expression". This, in the U.S., because a work must be "original", you can't copyright the "work" "ABCDEFGHIJKLMNOPQRSTUVWXYZ", and because it must be a "specific expression", you can copyright a novel in which the major plot events are "boy meets girl; boy gets girl; boy loses girl; grief-stricken boy commits suicide", but you cannot copyright all possible novels that feature those events. Broadly, a "license" means permission from someone who has an exclusive privilege to do something that allows someone else to do. For instance, I can grant you a "license" to hunt and fish on my land, or chop trees down on my property. A "copyright license" thus means that I, for instance, can grant you permission to duplicate, modify, and/or distribute a copyrighted work of mine. Ordinarily you would have no permission to do so because the government has granted me an exclusive, monopolistic privelege in those activities under the letter of copyright law. As with most laws, there are exceptions to the exclusive privilege of copyright. One such exception is known as "fair use". Unfortunately, copyright is poorly understood by the layman, and opportunistically exploited by large corporations that possess lots of copyrights, often by virtue of compelling the original authors to sign their copyrights over to the company. I hope this helps.  meaning that these monopoly privileges can be bought and sold -- G.
