The Generation Characteristics of English Abbreviation English abbreviations of word formation are to follow certain rules. Clipping A way which is widely used to form abbreviation is clipping, a process of cutting off the certain part or parts of a word to make up its abbreviation form① . A great number of English words have undergone the process of clipping happens in different ways: Cutting the Final Part. One of the ways in which clipping happens is cutting the final part of a word and left the initial part (or sometimes with a slight variation). This is one of the most usual ways to form abbreviation. It happens like that: Doc — doctor。 gas — gasoline. Cutting the Initial Part. This is another mon means by which abbreviations are formed. The final part is left and used to stand for the original word. For example: copter — helicopter。 script — prescription. Cutting either the Initial Part or the Final Part. Some clipping words are created by this means and either of the two parts can 黑河學(xué)院 本科生 畢業(yè)論文（設(shè)計(jì)） 7 represent its form. Some examples here can explain this point clearly. For example: heli copter — helicopter, roller coaster — roller coaster. In these two examples, either “heli” or “copter” can stand for the word “helicopter”, so that people will never be confused. The same thing happens to “roller” and “coaster”, to cut the other syllables of a word and with only the initial syllable left. Sometimes, abbreviation form when the first syllables of each word in a word group are left and other syllables cut off. For instance: CRUDIV — Cruiser Division, HICOM — High Command. Blending Blending refers to two or more than two words synthesis, and synthesis abbreviated is called the word of patchwork② . There are four main kinds: 1) The first part of the word before + the after part of the second word, for example, brunch (breakfast + lunch), Oxbridge (Oxford + Cambridge). 2) The first part of the word before + the first part of the second word, for example, sit (situation + edy), modern (modulator + demodulator). 3) The first part of the word before + all of the second word, For example, medicate (medical + care), lancing (language + sign). 4) All of the first language + the after part of the second word, workfare (work + welfare), travelogue (travel + logue). Acronym Acronym is made up from the first letters of the name of an anization which has a heavily modified headword, or the first letters of an extremely long word or word group in science, technology and other special fields, such as, CAD (Computer Assisted Design)。 Email — electric mail (electronic mail), etc. Digital Abbreviation This method is that figures add thumbnail letters or a noun, such as the five senses (sight, hearing, touch and smell, taste)。 AD val. (AD valorem buy). This kind of abbreviation characteristic is of the lower case mostly, and all has the punctuation marks. Variant Law Variant law refers to according to the pronunciation of the letters to change the spelling, such as quick — quik。 pi: /. And some of the pronunciation rules of abbreviations words are the same with the pronunciation of the words, such as NATO / nei tou / (North Atlantic Treaty Organization)。 RD, rd (road highway), etc. In addition, some abbreviations began with a capital letter of thumbnail type. But with the development of language, some abbreviations are into new words, so use should be in lower case. For example: RADAR, radar (radio detecting and ranging, RADAR), etc. 黑河學(xué)院 本科生 畢業(yè)論文（設(shè)計(jì)） 10 Some of the abbreviations can not ignore the symbols.
