One agent says a word which distinguishes one object in the scene from all the others.

The hearer checks the word against its own vocabulary.

The hearer understands the word 'wabaku' to mean 'red'.

As the agents learn each other's words, they begin to be able to communicate. In this example, the hearer has successfully recognised that the word 'wabaku' denotes a particular shade of red, and has been able to identify the object that the speaker has in mind.
