30.Define the ways of formation of blending, reduplication and sound-interchange.

The term blending is used to designate the method of merging parts of words into one new word; the result is a blend, also known as a portmanteau word. Blends are words formed from a word-group or two synonyms. In blends two way of word-building are combined: abbreviation and composition. To form a blend we clip the end of the first component and the beginning of the second component. As a result we have a compound-shortened word. One of the first blends in English was the word “smog” from two synonyms smoke and fog which means smoke mixed with fog. Cinemadict from cinema addict, chunnel from canal and channel, dramedy from drama and comedy, faction from fact fiction-fiction based on real facts, informecial from information commercial, medicare from medical care, slanguist from slang linguist.

Blending: Parts (which are not morphemes!) of two already-existing words are put together to form a new word. Examples: motel (motor hotel) brunch (breakfast & lunch), smog (smoke & fog), telethon (television & marathon), modem (modulator & demodulator), Spanglish (Spanish & English). 

Reduplication

New words are made by doubling a stem either without any phonetic changes or with a varation of the root vowel or consonant as in ping-pong, chit-chat, bye-bye, stylistically speaking most words are made by reduplication represent informal groups colloquialisms and slang.

Reduplication is the morphological process by which a morpheme is repeated, thereby creating a new word with a different word class. There are two types of reduplication: partial which reduplicates only part of the morpheme and full in which the entire morpheme is reduplicated.

Sound-interchange

They may be defined as an opposition in which words or word forms are differentiated due to an alternation in the phonemic composition of the root. It means some sounds are changed to form a new word. It is non-productive in Modern English, it was productive in old English and can be met in other Indo-European languages. In many cases we have vowel and consonant interchange. In nouns we have voiceless consonants and in verbs we have corresponding voiced consonants because in old English these consonants in nouns were at the end of the word and in verbs in the intervocal position. F: life-to live, blood-to bleed, hot-to heat, to sing-song.

31. Define the ways of formation of back-formation, sound-imitation and shortenings.

Backformation: A suffix identifiable from other words is cut off of a base which has previously not been a word; that base then is used as a root, and becomes a word through widespread use. Examples: pronunciate (< pronunciation < pronounce), resurrect (< resurrection), enthuse (< enthusiasm), self-destruct (< self-destruction < destroy), burgle (< burglar), attrit (< attrition), burger (< hamburger). This differs from clipping in that, in clipping, some phonological part of the word which is not interpretable as an affix or word is cut off (e.g. the '-essor' of 'professor' is not a suffix or word; nor is the '-ther' of 'brother'. In backformation, the bit chopped off is a recognizable affix or word ('ham ' in 'hamburger'), '-ion' in 'self-destruction'. Backformation is the result of a false but plausible morphological analysis of the word; clipping is a strictly phonological process that is used to make the word shorter. Clipping is based on syllable structure, not morphological analysis. It is impossible for you to recognize backformed words or come up with examples from your own knowledge of English, unless you already know the history of the word. Most people do not know the history of the words they know; this is normal. 

Sound imitation

Words are made by imitating different kinds of sounds that may be produced by animals, birds, insects, human beings and inanimated objects. It is the way of word-building when a word is formed by imitating different sounds. a) sounds produced by human beings, to whisper, to giggle, to mumble, to sneeze, to whistle; b) sounds produced by animals, birds, insects, to hiss, to buzz, to bark, to moo; c) sounds produced by nature and objects, to splash, to rustle, to clatter, to bubble, to tinkle.

Shortening is a comparatively new way of word-building has achieved a high degree of productivity, especially in American English.

Shortenings are produced in two different ways. The first is to make a new word of syllable of the original word. The latter may lose its beginning (as in phone made from telephone, fence from defence), its ending (as in hols from holidays, vac from vacation, ad from advertisement) or both the beginning and ending (as flu from influenza, fridge from refrigerator).

The second way of shortening is to make a new word from the initial letters of a word group: U.N.O., B.B.C., M.P. this type is called initial shortenings.
