Right, the key part is that a word is basically a label that triggers activation of a set of concepts in our minds. And we each have our own concepts associated with it based on our own personal experience in life. In a way we can never convey the exact meaning of our thinking to another person.

If one person explains something to another, and they interpret it in a novel way then an idea that neither person originally had could be produced as a result.
