Modern English Lexicology is closelyconnected with other branches of linguistics, because the word, word-groups andphrases are studied in several branches of linguistics and not in lexicologyonly. Lexicology is linked with general linguistics, the history of thelanguage, phonetics, stylistics, grammar and such new branches of our scienceas sociolinguistics and some others:

· Phonetics investigates thephonetic structure of a language which is mainly concerned with the functioningof phonetic units and studies the outer sound-form of the word i.e. its systemof phonemes and intonation patterns.

· Grammar is the study of thegrammatical structure or grammatical system of a language. It is concerned withvarious meanings of expressing grammatical relations between words as well aswith patterns after which words are combined into word-groups and sentences.The ties between lexicology and grammar are particularly strong in the sphereof word-formation which before lexicology became a separate branch oflinguistics had even been considered as part of grammar. The characteristicfeatures of English word-building, the morphological structure of the Englishword are dependent upon the peculiarity of the English grammatical system.

· The History of the Englishlanguage covers the main events in the historical development of the language:the history of its phonetic structure and spelling, the evolution of itsgrammatical system, the growth of its vocabulary.

· Stylistics studies manyproblems treated in lexicology, which are concerned with the study of nature,functions and structure of stylistic devices, on the one hand, and with theresearch of each style of language, on the other, i.e. with its aim, itsstructure, its characteristic features and the effect it produces as well asits interrelation with the other styles of language.

· Sociolinguistics investigatesthe social reasons of the changes in the vocabulary of a language which isdirectly and immediately reacts to developing and changes in social life. Therapid development of science, industry and technology gives a great number ofnew words, e.g. CD/DVD drive – a small compact disc on which sound orinformation is recorded. CDs are played on a special machine called CD player;Webcam – a video camera that is connected to a computer so that what it recordscan be seen on a website as it happens;

Flat-screen TV (also flat-panel),Flat-screen computer – a type of television or computer monitor that is verythin when compared with the traditional type. Thus, Modern EnglishLexicology investigates two main parts: the treatment of the English word as astructure and the treatment of the English vocabulary as a system. The courseof Modern English Lexicology studies the morphological and semanticpatterns according to which the elements of this system are built. It pointsout the distinctive features with the main semantically relevant partialdifferences between partially similar elements of the vocabulary which can besystematized and the course tries to explain how these vocabulary patterns areconditioned by the structure of the language.
