Özet:

Investigating the functioning of the language, a means of expression of thought and the abstract system created in the human mind, constitutes the basis for research on language. In this regard, the object of language is examined within the framework of different theories in formalist and functionalist approaches. Since the theories discussed within the scope of formalist and functionalist approaches show different representations, theories about the components of language and the interfaces formed by these components try to explain the language system by employing different methods. While the formal analysis is based on the internal structure of the language in an intuitive way, functional analysis is based on the communication dimension of the language, taking into account the context in which the language is used. The aim of this study is to discuss the basic components of the grammar that constitutes the language system, the linguistic interfaces formed by these components in accordance with the formalist approaches and to evaluate them through examples. Therefore, on the basis of formalist approaches, the representation of information about the fields including phonology, morphology, syntax, semantics and pragmatics (information structure) in addition to presenting theories about the phonology-morphology interface, morphology-syntax interface, phonology-syntax interface, phonology-semantics interface, morphology-semantics interface, syntax-semantics interface, syntax-pragmatics interface and phonology-morphology-semantics-syntax interface will be discussed in terms of their representations. To this end, it is aimed that the theories, assumptions and arguments related to the interfaces mentioned in the study will be the source by creating a theoretical framework for the interdisciplinary studies in linguistics literature.
