Close ties between lexicology and sociolinguistics

2.THE MAIN PROBLEMS OF MODERN LEXICOLOGY
The term «lexicology» is of Greek origin / from «lexis» - «word» and «logos» - «science». Lexicology is the part of linguistics, which deals with the vocabulary and characteristic features of words and word-groups.
The term «vocabulary» is used to denote the system of words and word-groups that the language possesses.
The term «word» denotes the main lexical unit of a language resulting from the association of a group of sounds with a meaning. This unit is used in grammatical functions characteristic of it. It is the smallest unit of a language, which can stand alone as a complete utterance.
The term «word-group» denotes a group of words which exists in the language as a ready-made unit, has the unity of meaning, the unity of syntactical function, e.g. the word-group «as loose as a goose» means «clumsy» and is used in a sentence as a predicative / He is as loose as a goose/.
Lexicology can study the development of the vocabulary, the origin of words and word-groups, their semantic relations and the development of their sound form and meaning. In this case it is called historical lexicology.
Another branch of lexicology is called descriptive and studies the vocabulary at a definite stage of its development.
Lexicology is a branch of linguistics – the science of language. The literal meaning of the term “lexicology” is “the science of the word”. Lexicology as a branch of linguistics has its own aims & methods of scientific research. Its basic task – being a study & systematic description of vocabulary in respect to its origin, development & its current use. Lexicology is concerned with words, variable word-groups, phraseological units & morphemes, which make up words.
Distinction is made between GENERAL LEXICOLOGY & SPECIAL LEXICOLOGY. General lexicology is a part of General linguistics. It is concerned with the study of vocabulary irrespective of the specific features of any particular language. Special lexicology is the lexicology of a particular language.
Lexicology is closely connected with other branches of linguistics: phonetics, for example, investigates the phonetic structure of language & is concerned with the study of the outer sound-form of the word. Grammar is the study of the grammatical structure of language. It is concerned with the various means of expressing grammatical relations between words as well as with patterns after which words are combined into word-groups & sentences. There is also a close relationship between lexicology & stylistics, which is concerned with a study of a nature, functions & styles of languages.
Lexicology – 'science of the word', a branch of linguistics, which basic task is a study and systematic description of vocabulary in respect to its origin, development and current use.
