【正确答案】正确答案：New words or expressions are created through the following processes excepted compound and derivation, which are called lexical change proper. (1)Initialism Some new words are composed of the first letters of a series of words and pronounced by saying each letter in them. Words of this kind such as VIP, WTO are called initialisms. (2)Abbreviation Many English words have come into being through abbreviation. This phenomenon is also called clipping; a new can be created by: i. cutting the final part, for example, ad for advertisement. ii. cutting the initial part, for example, plane for aeroplane. iii. cutting both the initial and final parts accordingly, for instance, fridge for refrigerator. (3)Blending is a relatively complex form of compounding, in which two words are blended by joining together the initial part of the first word and the final part of the second word, or by only joining the initial parts of the two words, for example, emotion + icon→emoticon; car + hijacking→carjacking. (4)Acronym is made up from the first letters of the name of an organization, which has heavily modified headword; an example is EU for European Union. This process is also widely used in shortening extremely long words of word groups in science, technology and other special fields, for example, SARS is short for "Severe Acute Respiratory Syndrome". What"s more, people also use this process in internet chatting or e-mail communication, such as BTW for "by the way" , ASAP for "as soon as possible".
