"Any text in spoken English is organized into what may be called 'information units'. (...) this is not determined (...) by constituent structure. Rather could it be said that the distribution of information specifies a distinct structure on a different plan. (...) Information structure is realized phonologically by 'tonality', the distribution of the text into tone groups."

"It is part of the task of linguistics to describe texts, and all texts, including those prose or verse, which fall within any definition of literature and are accessible to analysis by the existing methods of linguistics."

"We should not, perhaps, take it for granted that a description in terms of a formalised model, which has certain properties lacking in those derived from models of another kind, will necessarily be the best description for all of the very diverse purposes for which the descriptions of languages are needed. In assessing the value of a description, it is reasonable to ask whether it has proved useful for the purposes for which it was intended."

"Saussure took the sign as the organizing concept for linguistic structure, using it to express the conventional nature of language in the phrase "l'arbitraire du signe". This has the effect of highlighting what is, in fact, the one point of arbitrariness in the system, namely the phonological shape of words, and hence allows the non-arbitrariness of the rest to emerge with greater clarity. An example of something that is distinctly non-arbitrary is the way different kinds of meaning in language are expressed by different kinds of grammatical structure, as appears when linguistic structure is interpreted in functional terms."

"A child learning his [her] mother tongue is learning how to name; he [she] is building up a meaning potential in respect of a limited number of social functions. These functions [instrumental, regulatory, interactional, personal, heuristic, and imaginative] constitute the semiotic environment of a very small child, and may be thought of as universals of human culture"

"Traditionally, grammar has always been a grammar of written language: and it has always been a product grammar" ['Product' is here used as one term of the Hjelmslevian pair process/product.] A process/product distinction is a relevant one for linguists because it corresponds to that between our experience of speech and our experience of writing: writing exists whereas speech happens."

"The text is a product in the sense that it is an output, something that can be recorded and studied, having a certain construction that can be represented in systematic terms. It is a process in the sense of a continuous process of semantic choice, a movement through the network of meaning potential, with each set of choices constituting the environment for a further set."

"The human sciences have to assume at least an equal responsibility in establishing the foundations of knowledge."

"I see it as part of the development of the field. I would always emphasize how much I share with other linguists: I've never either felt particularly distinct or wanted to be distinct. I never saw myself as a theorist; I only became interested in theory, in the first place, because, in the theoretical approaches that I had access to, I didn't find certain areas developed enough to enable me to explore the questions that I was interested in."

"A physical system is just that: a physical system. What is systematized is matter itself, and the processes in which the system is realized are also material. But a biological system is more complex: it is both biological and physical — it is matter with the added component of life; and a social system is more complex still: it is physical, and biological, with the added component of social order, or value. … A semiotic system is still one step further in complexity: it is physical, and biological, and social —and also semiotic: what is being systematized is meaning. In evolutionary terms, it is a system of the fourth order of complexity"

"[... language, as an example of a semiotic system, contains all four levels of organization as follows:] First, it is transmitted physically, by sound waves traveling through the air; secondly, it is produced and received biologically, by the human brain and its associated organs of speech and hearing; thirdly it is exchanged socially, in contexts set up and defined by the social structure; and fourthly it is organized semiotically as a system of meanings"

"In the relative orientation of different social groups towards the various functions of language in given contexts and towards the different areas of meaning that may be explored within a given function"

"The grammatical system has … a functional input and a structural output; it provides the mechanism for different functions to be combined in one utterance"

"[interpersonal meaning] embodies all use of language to express social and personal relations, including all forms of the speaker's intrusion into the speech situation and the speech act."

"Language... is a range of possibilities, and an open end set of options in behavior that are available to the individual in his existence as social man. The context of culture is the environment of any particular selection that is made within them... The context of culture defines the potential, the range of possibilities that are open. The actual choice among these possibilities takes place within a given context of situation."

"Foregrounding, as I understand it, is prominence that is motivated"

"… language has evolved in the service of particular human needs … what is really significant is that this functional principle is carried over and built into the grammar, so that the internal organization of the grammar system is also functional in character."

"[The construal of context as a semiotic construct accompanies the construal of language as a metafunctionally organized system because of the realizational relationship between the two. And it is this relationship which helps to explain how language is learned:] It is this that enables, and disposes, the child to learn the lexicogrammar: since the system is organized along functional lines, it relates closely to what the child can see language doing as he observes it going on around him."

"What makes learning possible is that the coding imposed by the mother tongue corresponds to a possible mode of perception and interpretation of the environment. A green car can be analysed experientially as carness qualified by greenness, if that is the way the system works."

"The interpersonal function [of language] is the function “to establish, maintain, and specify relations between members of societies”"

"[A register is constituted by] the linguistic features which are typically associated with a configuration of situational features - with particular values of the field, mode and tenor."

"[Register] is set of meanings, the configuration of semantic patterns, that are typically drawn upon under the specified conditions, along with the words and structures that are used in the realization of these meanings."

"The theme is what is being talked about, the point of departure for the clause as message, and the speaker has within certain limits the option of selecting any element in the clause as thematic."

"The founder of systemic-functional linguistics, Michael Halliday pioneered the analysis of language in its social context. He convincingly reestablished the centrality of meaning in understanding how language functions after the domination of linguistic research by CHOMSKY's generative grammar model."

"In 1978, Michael halliday wrote Language as Social Semiotic, which revolutionized the way that we think about language in context"
