Words can be classifi ed according to the period of their life in the language. The number of new words in a language is always larger than the number of words which come out of active usage. Accordingly we can have archaisms, that words which have come out of active usage. Archaisms are words which are no longer used in everyday speech, which have been ousted by their synonyms. Archaisms remain in the language, but they are used as stylistic devices to express solemnity. Most of these words are lexical archaisms and they are stylistic synonyms of words which ousted them from the neutral style. Some of them are: steed /horse/, slay /kill/, behold /see/, perchance /perhaps/, woe /sorrow/ etc. Sometimes a lexical archaism begins a new life, getting a new meaning, then the old meaning becomes a semantic archaism, e.g. «fair» in the meaning «beautiful» is a semantic archaism, but in the meaning «blond» it belongs to the neutral style. Sometimes the root of the word remains and the affi x is changed, then the old affi x is considered to be a morphemic archaism, e.g. «beautious» /»ous» was substituted by «ful»/, «bepaint» / «be» was dropped/, «darksome» /»some» was dropped/, «oft» / «en» was added/. etc.
