First of all you will never see the word message mentioned in those languages you mentioned Second the word , understood, says nothing about the nature of the problem to a beginner Is it that the method does not exist ? Or is it that method exists but message does not ? Or is it that the method does something it should not ? Or is the VM that has problem executing the method ?

"Message(method) does not exist" happens in C/Java/etc when we *call* a method. "Message not understood by an object" happens in Smalltalk/Ruby when we *send* a message.
I like this conceptual distinguishment between calling a method and sending a message.
