Actuality of the course work is important, because the solution of the problems of prefixes and translation will make it possible to find nearly all question of word formation in the present-day lexicology.
The theoretical significance of the present course work is seen in the fact that it will give the language learners and translators to work out recommendations on how to work with English prefixes in the process of translation and what ways are applicable in the process of translation.
The practical value of the course work. The material, methods, results and conclusion of the work can be helpful for the teachers and students of the translation faculty in learning theoretical courses of translation theory and lexicology, also the practical courses, learned at the faculty.
The aim of the course work is to carry out a detailed investigation of prefixation as a means of word formation in English and their translation into Uzbek.
The tasks of the course work have been worked out on the basis of the aim of thework:
1. to define prefixation as word formation
2. to analyze the types of prefixes
3. to analyze the existing theories about word formation and prefixation in present day lexicology
4. to analyze the classification of prefixes
5. to analyze the affection of prefixes on lexical meaning
6. to analyze the ways of translating the English prefixes into Uzbek with a special attention paid.
CHAPTER I. MINOR TYPES OF WORD BUILDING
1.1. Types of Forming Words. General Issues
In English language we define two main ways of making new words: internal and external. Internal way means updating of language vocabulary due to its internal potential. It is a productive way of word manufacturing. Internal way includes conversion, affixation, compression, abbreviation, desaffixation. External way means loanwords. The main types of word building include inflection and derivation. Typically inflection contributes a morpheme that is required in order to ensure that the word has a form that is appropriate for the grammatical context in which it is used (tall-taller). Whereas inflection is driven by the requirement to form a word with the appropriate form in a particular grammatical context, derivation is motivated by the desire to create new lexical items using preexisting morphemes and words. When you need a new word, you do not usually need to make it up from scratch. It is possible to create new lexical items by recycling preexisting material. This is derivation. It takes one of these forms: affixation, conversion, stress placement or compounding. Let's briefly examine them. Conversion is a way of word-formation without affix use as a result of which is formed categorically different word conterminous in some forms with initial word (the story was filmed). Affixation is a way of new words formation by addition of word-formation affixes to the word stem (superwar, smarty, cuty, environmentalist). Desaffixation is a way of word-formation at which words are formed by rejection of a suffix or an element externally similar to a suffix (beggar - to beg, legislator - to legislate, burglar - to burgle). Abbreviation means formation of new words by reduction (truncation of word stem). As a result new words are formed with the incomplete, truncated word stem (or stems), called abbreviations (sis - sister, prof - professor, sec - second, dif - difference).¹
