In this chapter we defined verbal communication as an agreed-upon and rule-governed system of symbols used to share meaning. These symbols are arbitrary, ambiguous, and abstract. The rules that dictate our use and understanding of symbols include phonology, semantics, syntactics, and pragmatics. As you recall there are distinct differences between written and spoken forms of verbal communication in terms of levels of formality, synchronicity, recording, and privacy. Yet, new technologies are beginning to blur some of these differences. Finally, verbal communication is central to our identity as humans and it allows us to define reality, organize ideas and experiences into categories, help us think, and shape out attitudes about the world.
