However, learning English is not an easy work. During the process of learning English, people face many problems. The traditional Chinese culture is different from that of English-speaking countries. Whats more, in English there are a lot of slangs and idioms which are the obstacles to learning English. The other big block is the vocabulary. As we all know, there are some rules in forming Chinese characters. For instance, some characters we dont know them before, but when we see it we can guess the pronunciation and the meaning, because Chinese character is formed by several parts except some simple characters which can not be further divided into smaller components. Each part has its own meaning and pronunciation, so we can guess the whole meaning of the character from each part of it. Above all, there are many rules in studying Chinese characters, which help us remember more characters. It is also true in studying English, especially in learning English vocabulary. This paper, through the description of the composition of words and the ways of word formation, tries to offer the English leaners a better understanding of English vocabulary and some better ways of teaching English in order to help them find their own beat way to remember words. Key Words: definitions; classifications;word formation I. Introduction Words play an essential role in learning English. Words like the fundation of a house. Only if we study words well can we learn English well. Many professors and researchers devoted themselves to the word formation and left many useful methods for learning words. This can help English learners learn words in a more effective way. Though we human beings have showed interest in word formation for thousands of years, there still remain many open issues “in this most secret area of language study“ (Bauer 1983: 293). Recent years, more and more researchers are studying how to study English in an effective way. Some research the influence of culture. Some research the difference of grammar between Chinese and English. Some others would like to study the influence of word formation in the process of English learning. This paper centers on the study of word formation. At present, the main branches of word formation studied include inflection, derivation, compounds, invention, blending, abbreviation, acronym, back-formation, analogical creation, and borrowing and phonetic was also found influence the formation of words. II. The Definition and Classification of Words 1. The Main Definitions of Words When we learn words, we must know what is word, the main classification of words, and how words are formed. What is word? This question has been discussed for ages and numerous definitions have been suggested, but there is not a very clear and perfect definition of the words. However, when we talk about a word we can recognize it from the following aspects. Firstly, we can see it from the visual terms. In this line a word can be defined as a meaningful group of letters printed or written horizontally across a piece of paper. Secondly, we can recognize a word from the terms of spoken language, a word is viewed as a sound or combination of sounds which are made voluntarily with human vocal equipment. Human 2vocal organs can help us make sounds, and sounds can form words. Thirdly, according to semanticists, a word is a unit of meaning. At last we can recognize it on the grammatical level, that is a word should be a free form that can function in a sentence. To sum up, the definition of a word comprises the following points: A minimal free form of a languageA sound unit A unit of meaning A form that can function alone in a sentence According to Linguistics A Course Book (Hu, 2006), “a word is a unit of expression t
