Phraseology. Lexicography
The vocabulary of a language is enriched not only by words but also by phraseological units. Phraseological units are word-groups that cannot be made in the process of speech, they exist in the language as ready-made units. They are compiled in special dictionaries. The same as words phraseological units express a single notion and are used in a sentence as one part of it. American and British lexicographers call such units «idioms». We can mention such dictionaries as: L.Smith «Words and Idioms», V.Collins «A Book of English Idioms» etc. In these dictionaries we can find words, peculiar in their semantics (idiomatic), side by side with word-groups and sentences. In these dictionaries they are arranged, as a rule, into different semantic groups.
Phraseological units can be classified according to the ways they are formed, according to the degree of the motivation of their meaning, according to their structure and according to their part-of-speech meaning.

Examples

1. Rome was not built in a day.

2. Patience is a plaster for all sores.

3. Measure thrice and cut once.

4. Learn wisdom by the follies of others.

5. Judge not of men and things at first sight.

6. He jests at scars that never felt a wound.

7. He knows best what good is that has endured evil.

8. Curses like chickens come home to roost.

9. Custom is a second nature.

10. Everybody’s business is nobody’s business.
