Systemic functional grammar (SFG) is a form of grammatical description originated by Michael Halliday. It is part of a social semiotic approach to language called systemic functional linguistics. In these two terms, systemic refers to the view of language as "a network of systems, or interrelated sets of options for making meaning"; functional refers to Halliday's view that language is as it is because of what it has evolved to do (see Metafunction). Thus, what he refers to as the multidimensional architecture of language "reflects the multidimensional nature of human experience and interpersonal relations".
Influences Halliday describes his grammar as built on the work of Saussure, Louis Hjelmslev, Malinowski, J.R. Firth, and the Prague school linguists. In addition, he drew on the work of the American anthropological linguists Boas, Sapir and Whorf. His "main inspiration" was Firth, to whom he owes, among other things, the notion of language as a system. Among American linguists, Whorf had "the most profound effect on my own thinking". Whorf "showed how it is that human beings do not all mean alike, and how their unconscious ways of meaning are among the most significant manifestations of their culture". From his studies in China, he lists Luo Changpei and Wang Li as two scholars from whom he gained "new and exciting insights into language". He credits Luo for giving him a diachronic perspective and insights into a non-Indo-European language family. From Wang Li he learnt "many things, including research methods in dialectology, the semantic basis of grammar, and the history of linguistics in China".
Basic tenets Some interrelated key terms underpin Halliday's approach to grammar, which forms part of his account of how language works. These concepts are: system, (meta)function, and rank. Another key term is lexicogrammar. In this view, grammar and lexis are two ends of the same continuum. Analysis of the grammar is taken from a trinocular perspective, meaning from three different levels. So to look at lexicogrammar, it can be analysed from two more levels, 'above' (semantic) and 'below' (phonology). This grammar gives emphasis to the view from above. For Halliday, grammar is described as systems not as rules, on the basis that every grammatical structure involves a choice from a describable set of options. Language is thus a meaning potential. Grammarians in SF tradition use system networks to map the available options in a language. In relation to English, for instance, Halliday has described systems such as mood, agency, theme, etc. Halliday describes grammatical systems as closed, i.e. as having a finite set of options. By contrast, lexical sets are open systems, since new words come into a language all the time. These grammatical systems play a role in the construal of meanings of different kinds. This is the basis of Halliday's claim that language is meta-functionally organised. He argues that the raison d'être of language is meaning in social life, and for this reason all languages have three kinds of semantic components. All languages have resources for construing experience (the ideational component), resources for enacting humans' diverse and complex social relations (the interpersonal component), and resources for enabling these two kinds of meanings to come together in coherent text (the textual function). Each of the grammatical systems proposed by Halliday are related to these metafunctions. For instance, the grammatical system of 'mood' is considered to be centrally related to the expression of interpersonal meanings, 'process type' to the expression of experiential meanings, and 'theme' to the expression of textual meanings. Traditionally the "choices" are viewed in terms of either the content or the structure of the language used. In SFG, language is analysed in three ways (strata): semantics, phonology, and lexicogrammar. SFG presents a view of language in terms of both structure (grammar) and words (lexis). The term "lexicogrammar" describes this combined approach.
Metafunctions From early on in his account of language, Halliday has argued that it is inherently functional. His early papers on the grammar of English make reference to the "functional components" of language, as "generalized uses of language, which, since they seem to determine the nature of the language system, require to be incorporated into our account of that system." Halliday argues that this functional organization of language "determines the form taken by grammatical structure". Halliday refers to his functions of language as metafunctions. He proposes three general functions: the ideational, the interpersonal and the textual.
Ideational metafunction The ideational metafunction is the function for construing human experience. It is the means by which we make sense of "reality". Halliday divides the ideational into the logical and the experiential metafunctions. The logical metafunction refers to the grammatical resources for building up grammatical units into complexes, for instance, for combining two or more clauses into a clause complex. The experiential function refers to the grammatical resources involved in construing the flux of experience through the unit of the clause. The ideational metafunction reflects the contextual value of field, that is, the nature of the social process in which the language is implicated. An analysis of a text from the perspective of the ideational function involves inquiring into the choices in the grammatical system of "transitivity": that is, process types, participant types, circumstance types, combined with an analysis of the resources through which clauses are combined. Halliday's An Introduction to Functional Grammar (in the third edition, with revisions by Christian Matthiessen) sets out the description of these grammatical systems.
