I have now. The paper/quote shows that the closure uses a captured environment ("binding environment") instead of the environment that exists where the closure is called ("activation environment"). The environment of a closure is therefore fixed ("closed"). And that this is the source of the name closure.

Did *you* read it? Cause it defines a closure in terms of what variables it can access, just like I said.
