Functions of Language - Online First

Linguistics has embraced the functional and contextual turn but, when building tools for systematic contextual description, we have not made as much use as we could of our own functional traditions. Rather, we have largely relied on the metaphors of law and rule, which do not adequately capture tensions between consistency and variability in how language and context relate to each other. Our aim in this paper is to show the economy and practicality of representing context as a pathway through a network, drawing on the network technique for mapping systems of grammatical choice introduced by Michael Halliday, and on its application to other linguistic strata first offered by Ruqaiya Hasan. The paper begins by outlining why alternative frameworks are needed for describing context-language relations. We then present a contextual network for one specific domain of the Systemic Functional Linguistic notion of Tenor, namely social distance, and use this to explore how different configurations of features of social distance influence the way that traditions of practice are passed on as a specialised legacy in two different professional collaborations. While the kind of context modelling discussed here is in a very early phase of development compared to phonetic, morphological and grammatical description, it has many advantages: contextual networks are paradigmatic in orientation; they help display and theorise metastability in language; they are “ad hoc” in Firth’s positive sense; and they constitute a proposal to be tested against observed behaviour within specific cultural and situational settings.

‘Role’ is typically defined according to the part and/or function that something or someone contributes to a situation. This two-fold perspective is also inherent in discussions of the role of language: the ‘amount’ of language that is involved in a situation and the ‘function’ of language in a situation, with both perspectives relating to the non-linguistic systems that may be involved in the conduct of the situation relative to language. It is the latter of these perspectives, however, that has typically received most attention in discourse analysis, with the former (the ‘amount’) being left implicit and unproblematised. This paper considers the role of language from various discourse analytical perspectives before critically examining the concept within Systemic Functional Linguistics. Using system networks as the representational and analytical platform, the paper redefines ‘role of language’ in contextual Mode as comprised of two sub-systems: degree of involvement and type of involvement. degree of involvement accounts for the compositional contribution that language makes in a situation; type of involvement accounts for the way in which language may function in a situation. Using an illustrative dataset, the paper also demonstrates the effectiveness of the systemic approach in accounting for overlapping and differing contextual configurations by showing how features within the role of language configure and how these in turn configure with options in the Field system-network of action. These configurations are essentially hypotheses that can be more comprehensively tested through empirical research.
