It is known that the vocabulary of modern English language increases by 15 20 thousand lexical units each year. The reasons of such changes of the vocabulary composition are as follows: social and cultural changes within the modern society, technological “revolution” and globalization, etc. As we know, in English new words are formed in three main ways: inflection (adding two or more roots), affixation (using prefixes and suffixes) and conversion (changing from one part of speech to another without changing the form of a word).
The phenomenon of word formation is usually viewed from two perspectives: synchronic and diachronic. In the first approach, word formation is studied in the synchronic section of the language, where the focus is mainly on the links and relationships between words. Diachronic analysis of word formation allows us to look at the historical processes that accompanied this phenomenon throughout the formation of words [8].
