«In the beginning was the word» — it’s not just the words of the Bible, it is also a fact from the history of science, «Lexicology». The object of study of this science is the word and all that it involves: synonyms, antonyms, idioms, vocabulary of a language, the scope of the use of words and their stylistic coloring. Lexicology share in the total, which studies the vocabulary of any language, and private, engaged in separate language.
Private Lexicology: lexicology English
Lexicology of the English language is closely associated with many of the sciences, for example, with the style, t. To. There is often a need for choice of vocabulary, depending on the situation. The relationship can be seen in the words: grandmother — granny. From the point of view of English lexicology — a synonymous, only different shades of meaning. And for the style, it is important that these words should be used in a variety of styles: grandmother — in the official style, granny — in a conversational. Lexicology as science has many sub-divisions and is connected not only with the style. Meaning of the word has been semasiology (section lexicology). The composition of the word, together with lexicology deals with morphology, stable combinations — phraseology (section Lexicology), the origin of the word — etymology.
Lexicology of English studies the lexical structure of the language, which is closely linked with reality, resulting in relatively quick changes. The emergence of new words (neologisms) associated with the emergence of new realities (events and objects). But not everyone is sure to become the new word «neologism». Before they become, the word goes through several preliminary stages on which it disappears or, or «survive» in the language. Also, there is a process of gradual disappearance of words.
Changing the lexical structure of the language should not be associated only with archaisms or neologisms (words, obsolete). Changing the words also plays an important role. The reason for this process can be a reduction in the phrase: a musical (show), a weekly (paper). The remaining components of the absorbed value is lost.
The change of an existing phenomenon can also significantly change the meaning of the word. The verb to sail before the advent of the steam engine meant it was sailing, and after a significant step scientific and technical progress the verb came to refer to any smooth movement.
English vocabulary continues to be updated and replenished. Lexicology of the English language as a science created not only for the study of the word, but for the careful handling, because, as you say the word can not only heal, but to kill.
