Conclusion
Thus we can conclude that word formation as a means of the language development was widely studied by many linguists: foreign and native: and all of them agree that it is one of main ways of language replenishment and enriching.
Linguists state that word formation is that branch of lexicology which studies the deri
vative structure of existing words and the patterns on which a language, in this case English builds new words. We realize that the influx of new words has never been more rapid, than in the last few decades. It is due to advances in technology and communication.
Word formation ranges from prefixation and suffixation. We can conclude that the growth of the vocabulary reflects not only the general progress made by mankind but also the peculiarities of the way of life, of the speech community in which the new words appear, the way its science and culture tend to develop. Borrowing words from other languages word building provides for enlarging and enriching the vocabulary of the language.
In English there are two main ways of making new words: Internal and external.
Internal way means updating language vocabulary due to its internal potential. It is a productive way of word manufacturing.
Internal way includes conversation, affixation, compounding, abbreviation, desaffixation. External way means leanwords. The main types of word building include inflection and derivation. Inflection is driven by the requirement to form a word with the appropriate form in particular grammatical contest. Derivation is motivated by the desire to create new lexical items using preexisting morphemes and words. It is possible to create new lexical items by recycling preexsisting material. This is derivation. It takes one of these forms; affixation, conversion, sress placement or compounding.
Studying Reduplication we can sat that there are two separate methods, producing two different types or subsets of reduplication: phonological reduplication and morphological reduplication.
(1) Phonological duplication serves a phonological purpose; morphological reduplication serves a morphological process (either by being a word-formation process itself or by enabling another word-formation process to take place...).
Phonological duplication involves a single phonological segment. morphological reduplication involves an entire morphological constituent (affix, root, stem, word), potentially truncated to a prosodic constituent (mora, syllable, foot).
Phonological duplication involves, by definition, phonological identity, while morphological reduplication involves semantic, not necessarily phonological, identity.
Phonological duplication is local (a copied consonant is a copy of the closest consonant, for example), while morphological reduplication is not necessarily local
Just because reduplication in English isn’t a feature of the official grammatical system doesn’t mean it isn’t used in everyday discourse. Reduplication doesn’t stop willy-nilly once when language is acquired, though, and you might use reduplication as a type of wordplay in discourse. English speakers might use several types of reduplication, but perhaps the most common is contrastive focus reduplication. This is where a speaker emphatically contrasts a concept with a prototypical version of itself.
