What is linguistics and what is linguistics for

Linguistics in a broad sense includes philology. The study of language in a certain period of time is called synchronic linguistics; The study of the changes that a language undergoes over different periods of time is called diachronic linguistics or historical linguistics. The comprehensive study of linguistics and the attempt to find out the common rules of multiple languages is called general linguistics.

Applying linguistic knowledge to practical work is called applied linguistics. Tracing the kinship of certain languages through the comparison of phonetics and word forms is called historical comparative linguistics. The use of comparative methods to discover some common phenomena of various human languages is called typological linguistics.

Comparing the similarities and differences between two languages in order to solve a teaching or translation problem is called comparative linguistics. The disciplines of phonetics, grammar, vocabulary and writing, all of which focus on the structure of language itself, are the center of linguistics, some call microlinguistics. Phonetics is the study of the physical properties of speech, human pronunciation methods, and the physiological processes of speech perception.

Phonology or phonemics is the study of how many different sounds a language has, and how they differ and relate to each other. The study of the way words are formed and inflected is morphology, also known as lexicography; The study of how words are formed into phrases or sentences is the study of sentence formation, also known as syntax. According to traditional grammar, morphology and sentence formation are combined to form grammar.

Lexicology is the study of lexical items, lexical meanings, and the evolution of words; It is etymology that traces the ** and history of the word; Collecting many terms, classifying, comparing, and annotating them is lexicography. Semantics is the study of the relationship between words and concepts and referents, the similarities and differences, positive and negative, up and down, and intersection of various word meanings, and the analysis of the meaning of the whole sentence or some components therein. The discipline that studies the shape, system, origin, evolution, and development of writing is philology.

Including modern Chinese, ancient Chinese, etc., the main study is grammar. It's harder to learn.

The role of linguistics:

Language is a unique way of communication for human beings, reflecting the highly evolved mental capacity of human beings at the biological or psychological level, and the progress of human civilization at the social and cultural level. Linguistics is the study of the most core instinct of human language, through the analysis and study of spoken language, written language and even sign language, so as to understand the nature of human beings.

Linguistics is the study of human language, which explores the nature, function, structure, use, and historical development of language, as well as other language-related issues. In addition to understanding the nature of human language, linguistic research has a variety of applications. In terms of language education, through the understanding of the language itself, various dictionaries, grammar books, and textbooks are compiled for people to learn the language, and it also helps to improve the ability to cope with the difficulties and mistakes encountered in the process of language learning.

Language is the most important communication tool and thinking tool for human beings, and it is a variety of expression symbols for people to communicate. In other words, language is a symbol system that people use for social interaction with speech as the material shell, vocabulary as the ruler to search for building materials, and grammar as the construction rules. It is arbitrary and linear.

Linguistics, on the other hand, is a science that takes language as the object of study. The scope of exploration includes the nature, function, structure, use, and historical development of language, as well as other language-related issues. It is a scientific and systematic theoretical study of language.

The study of language in a certain period of time is called synchronic linguistics; The study of the changes that a language undergoes over different periods of time is called diachronic linguistics. There are many sub-disciplines of linguistics, such as phonetics, lexicology, grammar, rhetoric, and so on. In addition, linguistics can also form interdisciplinary disciplines with other disciplines, such as neurolinguistics, computational linguistics, psycholinguistics, sociolinguistics, and so on.

I don't know if I made it clear...

Language: It is the most important communication tool of human beings and the main way for people to communicate.

Linguistics: It is a discipline that takes human language as the research object, and explores the nature, function, structure, use and historical development of language in Suifeng Town, as well as other language-related issues. Linguistics is generally defined as a scientific and systematic theoretical study of language.

Language is a medium through which people communicate ideas, and it will inevitably have an impact on politics, economy and society, science and technology, and even culture itself. Language as a cultural phenomenon is constantly evolving, and its current spatial distribution is also the result of past developments. According to the commonality and origin of their phonetic, grammatical, and lexical characteristics, the world's languages are divided into language families.

Each language family includes a different number of languages, and these language families and languages have a certain distribution area in the region, and many cultural characteristics are closely related to this. Language refers to the sound (image) signals with a unified coding and decoding standard developed by biological beings due to the need for communication.
