In the Glossary, in the Beginners section at the below link:

The explanation regarding the "Receiver" is not understandable and very confusing. My suggestion is to simplify the explanation (the words) and maybe demonstrate the explanation with a clear example.

Specifically, even if we break the sentence down:
The receiver of a message send is the instance of a class..
implementing the method...
corresponding to the message...
sent receiving this message.
We still fail to understand what a receiver is.
