Language is a social tool. In the previous section, we referred to language as a shared code. By implication, this means that we need to interact with other humans to exchange information or share our feelings and ideas as humans. We use language in various ways when we communicate with other humans. We speak, we listen, we write, we draw or read. We stand closer to someone or further away. We communicate using gestures, facial expressions and other body language signals. We even communicate with the brand names and designer labels we proudly display! This sharing of meaning in verbal and nonverbal ways is the human species’ unique means of manifesting what they think or want others to think. This interaction consists of the encoding, transmitting and decoding of messages and is an active process in which both the sender and receiver need to make meaning. As early as the 4th century BC, the Chinese philosopher Confucius and his Greek and Roman counterparts Plato, Aristotle, Cicero and other intellectuals were already formulating ideas about human communication and its importance as a social skill. The essence of human communication, regardless of the size of the audience, is interpersonal engagement. The communication process is ongoing, initiated by a sender and responded to when the receiver gives feedback somehow. This repetitive communicative action, broadly speaking, never ceases but can be divided into various episodes and takes diverse forms, e.g., verbal and nonverbal communication. Anything that impedes communication has been labelled as noise. Noise does not only refer to actual sounds such as dogs barking, weed-eaters whining or jet planes flying overhead, which could be distracting or may distort the message. Instead, noise can also include the aspect of semantic noise, i.e., not comprehending the verbal code being used or even not having sufficient proficiency in that code. Noise includes sensory or external impressions and psychological or internal noise. Whether it is a stuffy or cold classroom or whether a learner is distressed or hungry, such noise negatively influences communication and thus leads to poor understanding (Cleary, 2003; Louw & Du Plooy-Cilliers, 2003; Erasmus-Kritzinger, Bowler & Goliath, 2001; Steinberg, 1995; Van Staden, Marx & Erasmus-Kritzinger, 2007).
Some cultures use words to describe a young child merely as a “thing” until they learn to talk. This approach to the young child suggests that one becomes a community member only once one has acquired the ability to express one’s needs and desires in speech. Furthermore, it is generally considered atypical for people to speak to themselves – strengthening the view that a language is a social tool.
