 Pizza, if I were to say that maybe in some remote place in the world where English had never penetrated or Italian had never penetrated, it would just sound like sounds. It would just sound like noises because the person wouldn't know what that meant. But when you know the language, you immediately convert that word symbol into an idea of a pizza. You know what a pizza looks like, what it smells like, what it tastes like. So this is a more primitive concept.
