Linguistics is the scientific study of language and there are several materials studied in linguistics called the linguistics field. In general, linguistics is the search for knowledge that people unconsciously have about language, an understanding of the structure of language, and knowledge of how different languages differ from one another. In various general dictionaries, linguistics is defined as the science of language or the scientific study of language.
The contribution of linguistics to language teaching is indirect. Therefore, the field of linguistics and language didactics is a separate field and becomes separate specialty. This does not mean, however, that they do not need each other, as they inevitably require linguistic elements, namely many related theories of linguistics that can be implemented in language learning and teaching. Linguistics only contributes indirectly in the form of materials.
Every science, no matter how theoretical, certainly has practical uses for human life. Likewise with linguistics. We can ask what are the advantages of studying linguistics. Linguistics will bring direct benefits to those involved in language-related activities, such as the linguists themselves, language teachers, translators, textbook makers, dictionary makers, information officers, journalists, politicians, diplomats, etc. The following are the advantages of linguistics, namely:
Firstly, for linguists themselves, extensive knowledge of linguistics will certainly be very helpful in fulfilling and carrying out their tasks. for researchers, politicians, and literary-linguistic enthusiasts, it will help them better understand literary works. Because language, the subject of linguistic research, is the place where literary works are created. It is impossible that we cannot understand literary works well without having a good knowledge of the nature and structure of language. In addition, it is important to remember that literary works use a special variety of languages that are not identical to common speech.
Secondly, language knowledge is very important for teachers, especially language teachers, starting with the sub-disciplines of phonology, morphology, syntax, semantics, and lexicology and ending with knowledge of the relationship between language and society and culture. How can a language teacher practice language skills if he doesn’t know phonology; How can he practice writing skills if he doesn’t know spelling, morphology, syntax, semantics, and lexicology?
In addition, as a language teacher, he not only has to practice language skills but also correctly explain the rules of the language. There are conflicting views between language teaching and linguistics. Instruction is prescriptive or normative while linguistics is descriptive. In the hands of a teacher versed in linguistics, the two different views can be understood. He will be able to formulate prescriptive rules from descriptive rules so that the lessons can work well.
Not only do language teachers need to have language skills, but teachers of other fields of study may also need to have this knowledge because as a teacher he is not constantly involved in language matters. Doesn’t he also have to explain his subject in language? If they have language skills, they can deliver their lessons more easily.
Third, language skills are essential for translators, not only in terms of morphology, syntax, and semantics but also in terms of sociolinguistics and contrastive linguistics.
Fourth, for dictionary compilers or lexicographers, mastery of linguistic aspects is necessary, since all linguistic knowledge brings advantages in the fulfillment of their tasks. To compose a dictionary he must begin by determining the phonemes of the language he wants to dictate, the spelling or graphemes of those phonemes, the intricacies of word form and formation, phrase structure, sentence structure, lexical meaning and to understand the grammar meaning, contextual meaning, and meaning, idiomatic, as well as the social background of the language. It would be impossible to create a dictionary without knowledge of all aspects of linguistics.
Fifth, language knowledge also benefits the creators of lessons or textbooks. Language skills will help textbook authors form the correct sentences and select vocabulary according to the age of the reader. Of course, books intended for primary school children must be in a different language than books intended for advanced children or universities as well as for the general public.
Sixth, the advantages of linguistics for statesmen or politicians, namely: (1) As a statesman or politician who has to fight for the ideology and concepts of state or government, he must have a good verbal command of the language. (2) when the politician or statesman copes with linguistic and sociolinguistic issues, especially related to society, due to language differences and contradictions. Physical clashes erupted in several multilingual countries such as India and Belgium due to language conflicts. It’s a shame when it’s just about the language people have to clash physically.
Language teaching activities are pedagogical, pedagogical grammar is a grammar containing language teaching and learning activities written by and for the language teaching and learning process. Informally, there is always information available about success or a particular approach or practice in language teaching. The classroom can be considered the most accessible laboratory of all for research. Since the priority of teaching is always the interest of the student’s education, there are limits to what can be achieved through language learning research. Some continue to argue that the role of teachers in what is often referred to as action research and linguistics can contribute both to assisting teachers in conducting such research and to efforts to provide a stronger empirical basis for assessment of learning and effectiveness in language learning.
