Traditionally, we associate the language concept with that of communication. In practice, however, this conceptual link is treated by linguists too loosely and arbitrarily. In the current study, we try to render the relationship of language to communication more transparent and accurate. We start by confronting the properties of speaking with those of other modes of human interaction. Such an approach helps us to gain a more adequate insight into the nature of language, its origins and its role in our life.
