What are the theories of systemic functional linguistics

Systemic functional linguistics consists of two parts, "systematic grammar" and "functional grammar", but this is not a simple sum of the two grammars, but a complete framework of language theory.

of two inseparable aspects.

Systematic grammar treats language as a regular resource, and its basic principle is that language describes systems more than structures. Systematic grammar or systemic linguistics focuses on the underlying relationship of language as a system, which is a system network of several subsystems associated with meaning that can be continuously selected by people, also known as "meaning potential". As a kind of symbol, language must be selected in each semantic function part of the language when expressing the semantics that the speaker wants to express.

This choice depends on all aspects of the context in which the language is used. This choice can be made at different levels of the language. In short, the content determines the form, and the form should be embodied by the substance.

Functional grammar states that language is social interaction.

tools. The language system is gradually formed by people in long-term communication in order to achieve a variety of different semantic functions. In the same way, when people make choices in a language system, it is also a motivated activity based on the function to be achieved.

Since language constructs reality, functional grammar must be built on everyday forms of language, which is an empirical theory.

The functions of language include: the carrier of cultural information (the means by which human beings comprehend the historical experience and artistic achievements of human society); a tool for people to understand the world (people use language to think and use language to regulate behavior); Communicative and means of exchanging ideas (the amount of information that language can carry can be applied to all spheres of life).

From the perspective of human relations, language is a means of communication and the exchange of ideas. According to psychologist Halliday, the process of language acquisition in children can be seen as a process of gradual acquisition of the various functions of language. Seven language features are proposed accordingly:

instrumental function, modulatory function, interaction (communication) function, personal expression function, heuristic function, imagination function, and information function.

NatureLanguage is a way of communication between people, and people can't do without language when they interact with each other. Although people's thoughts can be conveyed through **, movements, expressions, etc., language is the most important and the most convenient medium. However, people around the world speak different languages, and it is difficult, if not impossible, to speak directly to each other.

Even within the same language, there are different dialects with different degrees of difference. Some dialects can be largely understood by each other, while others are so different that they seem to be another language, and the incomprehension of Cantonese by Beijingers is a good example.

Linguistic theories include the nature, function, structure, application and historical development of language, as well as other language-related issues, and human language as the object of study. The task of linguistics is to study and describe the structure, function and historical development of language, to reveal the nature of language, and to explore the common laws of language. Linguistic theories include the nature, function, structure, use and historical development of language, as well as other language-related issues, and human language as the research object.

Introduction to linguistics, combined with reality, the functions of language are:

social function) and (thinking) function.

Correlation Theory, Conversational Meaning, Speech Act Theory, Cooperation Principle, Politeness Principle.

1. Correlation theory is a cognitive pragmatics theory. Proposed by Sperber and Caller in Relevance: Communication and Cognition. Based on the concept of relevance and the principle of relevance, this paper analyzes the discourse theory in verbal communication.

The principles of association include: the principle of cognition, that is, the tendency of human cognition to coincide with the greatest degree of relevance; The communicative burning principle states that every utterance (or other act of inferential communication) should be conceived as having the best relevance to the utterance or action itself. In correlation theory, relevance is seen as a property of discourse, thoughts, behaviors, situations, etc., that are fed into cognitive processes.

2. "Conversational implicature" was first proposed by the American philosopher Grice, which is the core content of pragmatics and plays a very important role in verbal communication. The theory of "conversational meaning" has attracted extensive attention in the philosophical and linguistic circles because of its novel and important content.

3. Speech act theory is a philosophical theory of language. Austin of Britain proposed it, and Searle et al. of the United States developed it. According to Austen, language is a peculiar way of human behavior, and people cannot do without speech behaviors such as speaking and writing in the actual process of communication.

The central topic of linguistic analytic philosophy should be the study of the nature and internal logical construction of this speech act.

4. The "principle of cooperation" was put forward by the famous American philosopher of language Grice in a lecture at Harvard University in 1967.

Grice believes that in the process of communication, the two sides of the dialogue seem to follow a certain principle, consciously or unconsciously, in order to cooperate effectively to complete the communicative task. Thus, Grice (who came up with the "cooperative principle" in conversation (CP).

In his book Principles of Pragmatics, the famous British scholar Leech expounded on the important role of politeness in linguistic communication. For the first time, he proposed the principle of politeness, which he considered to be two principles of communication with the principle of cooperation with Grice. Leech divides the principles of politeness into six categories, each consisting of one criterion and two sub-criteria.

There are 7 functions of learning a language, which are to make your life better, make your work better, and make your way of dealing with people better.

If you want this, study, study, the seven functions of language, the function of language is nothing, you will be able to express and speak normally, and your thinking logic will be improved.

If it is five yuan and ten yuan, the energy supply will probably be able to support it more.

The seven functions of linguistics are actually very important.
