Introduction Language is one of the basic elements of vocabulary, in the initial stages of language development, people are using small and simple vocabulary, the words say simple daily things and concepts, Original in the English new words are mostly monosyllabic, such as: the sun, the man, the head, foot, fish, see, run and so on, their number is limited. With society development and progress, the expansion of the language and the fusion make language becomes complex, the original limited original words is not enough, people created new some new word to say some things and concepts.The expansion of vocabulary in modern English depends chiefly on word formation. The most productive are derivation, compounding and conversion. Talking about word formation patterns means dealing with rules.2. Three basic word formation2.1 DerivationDerivation is the process of forming new words from existing ones by adding affixes to them. It also means affixation is defined as the formation of words by adding word-forming or derivational affixes to bases. The words that are created in this way are called derivatives. According to the position affixes occupy in words, there are two subcategories: pre-fixation and suffixation.Prefixation is the formation of new words by adding prefixes to bases, which do not generally change the word-class of the base. That is to say, prefixes do not change the part of speech of a word. Suffixation is the formation of new words by adding suffixes to bases. Their primary function is to change the grammatical function of the base, such as the change of the word class with a slight modification of meaning, though there are a few exceptions. For example, the word “countless”, “-less” change the part of form and show the negative meaning of the stem.Prefixes and suffixes are different in grammatical functions, semantic. Most suffix 1will change the part of speech of root, but most prefix do not affect the root and other grammatical category. In a word, derivation can help students enlarge their English vocabulary, let they remember words efficiently.2.2 CompoundingCompounding is the formation of new words by joining two or more bases. Words formed in this way are called compounds. In the process of English development, compounding plays an important role in formation. Compounding is one of the oldest methods of word-formation in English, and the compounding of compound is one of the features of Old English vocabulary. Compounding composition can have all kinds of word forms, and the combination is not restricted by grammar in the arrangement of word order in English. Compounding word formation of most materials provided by the basic vocabulary. 2.3 ConversionConversion is the formation of mew words by converting words of one part of speech to those of another part of speech. Conversion may lead students often confused with words which have two or more part of form in English learning. Words created in this way are new only in a grammatical sense. Words produced by conversion are primarily nouns, adjectives and verbs. It deserves nothing that conversion is not only a change of grammatical function of the item involved but with it the different range of meaning is originally carried.The biggest characteristic of conversion is the same word may have lots of meaning, the meaning can be similar, it also can be completely irrelevant.3.
