For Halliday, there is a "network of meanings" within a culture, that constitutes the "social semiotic" of that culture. This "social semiotic" is encoded and maintained by the discourse system of the culture.[5] For Halliday, contexts in which texts are produced recur, in what he calls "situation types." People raised within a specific culture become accustomed to the "situation types" that occur within that culture, and are more easily able to maneuver through the "situation types" within that culture than people who were not brought up within it.[6]
