Word-structure and word-formation
A lot of words in English have a composite nature and are made up of smaller units each having sound form and meaning.These smaller units are called morphemes.Eg.: teach-er, help-less-ness, sports-man.
Like a word, a morpheme is an association of a certain meaning with a certain sound-pattern. But unlike a word, a morpheme is not an autonomous unit and can occur in speech only as a constituent part of the word. Eg.: anti-inflammatory.
Semanticallymorphemes are classified into root morphemesand afflxational morphemes.Root morphemes are lexical centres of the words, the basic constituent parts of the words. Eg.: weak-ness teach-er common-ly.
Afflxational morphemesare prefixes and suffixes; they have a generalized lexical meaning and part-of-speech meaning: dis-comfort, re-read, beauty-ful,occurence.
Structurallymorphemes are divided into free, bound and semibound. Freemorphemes coincide with the stem, roots: day, week, friend. Boundmorphemes prefixes and suffixes, they are never used separately, but only as constituent parts of words: dis-, re-, ful-, -less etc. Semibound(semi-free) morphemes can function both as an affix and as a free morpheme. Eg. halfpast three, half-done; to do well, well-done.
Language is never stable: it undergoes changes on all its levels: phonetic, morphological, lexical, phraseological, etc.
As for some morphemes, in the course of time they may become fused to gether with the root, some root-morphemes may become affixes, polymorphic words may become monomorphic, compound words may become simple words. Eg.: hus-bond-a = хозяин, владелец дома —> husband - муж
wif-man = жена мужа —» woman - женщина The Latin term "-itis" means "inflammation" —» appendicitis.
There are different ways of forming words. Word-formation is the process of creating new words from the material available in the language after certain structural and semantic formulas and patterns.

There are productive and non-productive ways of word-formation. Productive ways are widely used to form a lot of new words. Non-productive ones are not used now to form new words, they are retained in a number of old words.
Productive ways of word-formation are:
3. Word-building: affixation
Affixation i§ the formation of new words by adding derivational affixes to different types of stems.
3.1. Word-building: prefixation
Prefixation is the formation of words with the help of prefixes. The^nay be classified into several groups on different principles: according to their origin, meaning, function and to the part of speech formed.
In the course of time English has adopted a great number of prefixes from foreign languages, not separately, but as constituent parts of borrowed words.
Quite a number of borrowed prefixes have become of international meaning: extra-, sub-, inter-, anti-, counter-, super-, etc.
Synchronic classifications of prefixesare classifications according to the meaning, to the part of speech formed, to stylistic reference and according to productivity. The first 2 are of greatest importance for translation of medical text.
