Chapter 4 examines social protocols in public discourse, representing the realm of ‘overly’ ordinary language use. The term ‘public discourse’ means both monologues and dialogues that take place in public, often through mediatised events or written (online) pieces which are available for, or even addressed to, members of the public. ‘Social protocols’ describe forms of language use associated with ‘politeness’ in public discourse specifically, where ‘politeness’ in the interpersonal sense is hardly needed, i.e., such forms at first sight may seem to be entirely ‘superfluous’ if not ‘redundant’. Because if this, while social protocols and mediatised public aggression (studied in Chapter 3) may appear to have little in common at first sight, interestingly both of them have an ‘unreasonable’ element. This sense of unreasonableness however dissolves once one looks at such forms of language use through the ritual perspective. As a case study, Chapter 4 examines the ritual conventions of social protocols in a corpus of Chinese public announcements made in the wake of a major social crisis.
