5. Retell the text. Language as a system

Language is a means of forming and storing ideas as reflections of reality and exchanging them in the process of human intercourse. Language is social by nature; it is insep­arably connected with the people who are its creators and users; it grows and develops together with the development of society.

Language incorporates the three constituent parts (‘sides’), each being inherent in it by virtue of its social nature. These parts are the phonological system, the lexical system, the grammatical system. Only the unity of these three elements forms a language; without any one of them there is no human language in the above sense.

The phonological system is the subfoundation of language; it determines the material (phonetical) appearance of its significative units. The lexical system is the whole set of naming means of language, that is, words and stable word groups. The grammatical system is the whole set of regularities determining the combination of naming means in the formation of utterances as the embodiment of thinking process.

Each of the three constituent parts of language is studied by a particular linguistic discipline. These disciplines, presenting a series of approaches to their particular objects of analysis, give the corresponding ‘descriptions’ of language consisting in ordered expositions of the constituent parts in question. Thus, the phonological description of language is effected by the science of phonology; the lexical description of language is effected by the science of lexicology; the grammatical description of language is effected by the science of grammar.

Any linguistic description may have a practical or theoretical purpose. A practical description is aimed at providing the student with a manual of practical mastery or the corresponding part of language (within the limits determined by various factors of educational destination and scientific possibilities). Since the practice of lingual intercourse, however, can only be realized by employing language as a unity of all its constituent parts, practical linguistic manuals more often than not comprise the three types of description presented in a complex. As for theoretical linguistic descriptions, they pursue analytical aims and therefore present the studied parts of language in relative isolation, so as to gain insights into their inner structure and expose the intrinsic mechanisms of their functioning. Hence, the aim of theoretical grammar of a language is to present a theoretical description of its grammatical system, i.e. to scientifically analyse and define its grammatical categories and study the mechanisms of grammatical formation of utterances out of words in the process of speech making.
