1 Analyze stem, root of the words, and give their types.

When a derivational or functional affix is stripped from the word, what remains is a stem. The stem expresses the lexical and the part of speech meaning. For the word hearty and for the paradigm heart(sing) – hearts(pl) the stem may be represented as heart-. This stem is a single morpheme, it contains nothing but the root, so it is a simple stem. It is also a free stem because it is homonymous to the word heart. A stem may also be defined as a part of the word that remains unchanged throughout its paradigm. The stem of the paradigm hearty – heartier (the) heartiest is hearty-. It is a free stem, but as it consists of a root morpheme and an affix, it is not simple but derived. Thus, a stem containing one or more affixes is a derived stem. If after deducing the affix the remaining stem is not homonymous to a separate word of a same root, we call it a bound stem. For example, in the word cordial the adjective-forming suffix can be separated on the analogy with such words as bronchial, radial, social. The remaining stem, however, cannot form a separate word by itself, it is bound. Bound stems are especially characteristic of loan words. Ex: French borrowings: arrogance, charity, courage, coward, which do not coincide with any semantically related independent words. Roots are main morphemic vehicles of a given idea in a given language at a given stage of its development. A root may be also regarded as the ultimate constituent element which remains after the removal of all functional and derivational affixes and does not admit any further analysis. Not all roots are free forms, the roots which capable of producing new words are productive roots. Ex: a morning’s drive, a morning’s ride, a morning’s walk.

2 Analyze the problems of Lexicology according to their importance in Lexicology.

The problems of Lexicology:

1)Word-formation

2)Semasiology and types of word meaning

3)Paradigmatic (synonymy and functional style) and syntagmatic relations of words

4)Phraseology

5)Lexicography. Types of dictionaries.

6)The study of vocabulary as a system.

The problem of word-building is associated with prevailing morphological word-structures and with processes of making new words. Semantics is the study of meaning. Modern approaches to this problem are characterized by two different levels of study: syntagmatic and paradigmatic.

On the syntagmatic level, the semantic structure of the word is analysed in its linear relationships with neighbouring words in connected speech. In other words, the semantic characteristics of the word are observed, described and studied on the basis of its typical contexts.

On the paradigmatic level, the word is studied in its relationships with other words in the vocabulary system. So, a word may be studied in comparison with other words of similar meaning.

Phraseology is the branch of lexicology specializing in word-groups which are characterized by stability of structure and transferred meaning.

One further important objective of lexicological studies is the study of the vocabulary of a language as a system. The vocabulary can be studied synchronically, that is, at a given stage of its development, or diachronically, that is, in the context of the processes through which it grew, developed and acquired its modern form.

Lexicography is the branch of lexicology that deals with the problems of dictionary compiling.
