In simple terms, a delegate is an object that helps the other object to do some stuff. The original object "delegates" the work to a delegate. In various sources, the term delegate might be loaded with additional meaning (you can read more about this on wiki), but in my course, it simply means passing some work to another object.
Please let me know if you have any further questions.
Is a delegate like a dependency or opposite of a dependably or how do they relate?
