Conclusion. We have dialled in detail with various types of semantic change. This is necessary not only because of the interest the various cases present in themselves but also because a thorough knowledge of these possibilities helps one to understand the semantic structure of English words at the present stage of their development. The development and change of the semantic structure of a word is always a source of qualitative and quantitative development of the vocabulary.
The constant development of industry, agriculture, trade and transport bring into being new objects and new notions. Words to name them are either borrowed or created from material already existing in the language and it often happens that new meanings are thus acquired by old words. LITERATURE 1. Rinaburg R.
