Introduction.

Phraseology is a scholarly approach to language which developed in the twentieth century [1]. It took its start when Charles Bally's notion of locutions phraseologiques entered Russian lexicologyand lexicography in the 1930s and 1940s and was subsequently developed in the former Soviet Union and other Eastern European countries. From the late 1960s on it established itself in (East) German linguistics but was also sporadically approached in English linguistics. The earliest English adaptations of phraseology are by Weinreich (1969) within the approach of transformational grammar), Arnold (1973), and Lipka (1992) [2].

In Great Britain as well as other Western European countries, phraseology has steadily been developed over the last twenty years. The activities of the European Society of Phraseology and the European Association for Lexicography with their regular conventions and publications attest to the prolific European interest in phraseology. Bibliographies of recent studies on English and general phraseology are included in Welte (1990) and specially collected in Cowie & Howarth (1996) whose bibliography is reproduced and continued on the internet and provides a rich source of the most recent publications in the field [3].

Phraseological Units and Word-group.

Phraseology is a branch of lexicology studying phraseological units (set expressions, praseologisms, or idioms (in foreign linguistics).

Phraseological units differ from free word-groups semantically and structurally:

1) they convey a single concept and their meaning is idiomatic, i.e. it is not a mere total of the meanings of their components

2) they are characterized by structural invariability (no word can be substituted for any component of a phraseological unit without destroying its sense (to have a bee in one’s bonnet (not cap or hat).

3) they are not created in speech but used as ready-made units.

A word-group is the largest two-facet lexical unit comprising more than one word but expressing one global concept.

The lexical meaning of the word groups is the combined lexical meaning of the component words. The meaning of the word groups is motivated by the meanings of the component members and is supported by the structural pattern. But it’s not a mere sum total of all these meanings! Polysemantic words are used in word groups only in 1 of their meanings. These meanings of the component words in such word groups are mutually interdependent and inseparable (blind man – «a human being unable to see», blind type – «the copy isn’t readable).

Word groups possess not only the lexical meaning, but also the meaning conveyed mainly by the pattern of arrangement of their constituents. The structural pattern of word groups is the carrier of a certain semantic component not necessarily dependent on the actual lexical meaning of its members (school grammar – «grammar which is taught in school», grammar school – «a type of school»). We have to distinguish between the structural meaning of a given type of word groups as such and the lexical meaning of its constituents.

Words put together to form lexical units make phrases or word-groups. One must recall that lexicology deals with words, word-forming morphemes and word-groups.

The degree of structural and semantic cohesion of word-groups may vary. Some word-groups, e.g. at least, point of view, by means, to take place, etc. seem to be functionally and semantically inseparable.

They are usually described as set phrases, word-equivalents or phraseological units and are studied by the branch of lexicology which is known as phraseology. In other word-groups such as to take lessons, kind to people, a week ago, the component-members seem to possess greater semantic and structural independence. Word-groups of this type are defined as free word-groups or phrases and are studied in syntax.

Structurally word-groups can be considered in different ways. Word-groups may be described as for the order and arrangement of the component-members. E.g., the word-group to read a book can be classified as a verbal-nominal group, to look at smb. – as a verbal-prepositional-nominal group, etc.
