Introduction: "Linguistic diversity captured with the terms style and register is of interest to literary theory and to linguistic theory, as both are concerned with how individuals and the multiple social groups and networks that they can simultaneously be members of articulate themselves and how they distinguish themselves from others, the reasons that speakers/writers may have for their choice of linguistic forms, the ways in which these linguistic forms can be creatively exploited in particular contexts as well as with the effects that the choices and departures from norms or conventions of use may have on the hearers/readers. Among the issues of common interest to literary and linguistic theory are the formal, cultural, historical, axiological, moral, ideological, social, psychological, hermeneutic, and other aspects of the structure, production and perception of language. These aspects are traditionally studied in relation to general concepts of convention and creativity, literalness and fictionality, objectivity and subjectivity, politeness and power, consensus and conflict, class and stigma, affect, personal identity and allegiance, and many others."(...)
