Phraseology continues to be subject to extensive, and often contradictory discussions, requiring, in terms of language, some more clarifi cation. Uncertainty and confusion in the field of phraseology is laid by a variety of names which are used to express units that build the subject matter of phraseology. As a reproductive unit of language a phraseological unit semantically presents a whole. Phraseological units are historic results of linguistic creativity. Recognized as ready-made constructions, the speaker does not create them on the occasion of speaking, but draws them form his mental lexicon. Language, however, tends to alter the standard form of phraseological units, and its intentions are different.
