^That's the definition of the word return. In this context, it's the act of returning data from the called method/function back to the method/function that called it. So lets say I created a method called public int GetSum(int a, int b).... Somewhere else in my code I would call that methood with GetSum(2,2); and then from the method GetSum() it would do its calculations to add the number and RETURN the result (or w/e) back to the code where I called GetSum() at. This is very useful when you want to return data back from a function so that you can use its results elsewhere.

Answer 2

To return means to give back. A void function for example does not return a value which means it cannot be assigned to a variable.
