A. Vocabulary

1. Definition of Vocabulary

Vocabulary as one of the language aspects is supposed to be learnt when people are learning a language. Good mastery of vocabulary is important for anyone who learns a language. A learner of foreign language will speak fluently and accurately, write easily, or understand what he reads or hears if he has enough vocabulary and has a capability of using it accurately. It is abvious that vocabulary is very important for learning a language, especially English, because the English vocabulary is extremely large and various. Therefore, it is highly essential for English teachers to help their students to understanding vocabulary. There are definitions of vocabulary given by experts. Penny Ur defines that vocabulary is the words that teach in the foreign language. 1 Hatch and Brown define vocabulary as a list or set of words for a particular language or set of words that individual speakers of language might use. 2 In Oxford Dictionary, vocabulary is defined as follows 3 : a. All the words that a person knows or uses. b. All the words in a particular language. c. The words that people use when they are talking about a particular subject. d. A list of words with their meanings, especially in a book for learning a foreign language. From the definition above, it shows that vocabulary is a component of language and number of words used by a person, class, profession, etc. In the communication and every aspect such as in trade, education, business, etc. 1 Penny Ur, A Course in Language Teaching Practice and Theory New York: Cambridge University Press, 1996, p. 60. 2 Evelyn hatch and Cerryl Brown, Vocabulary, Semantics, and Language Education Cambridge: Cambridge university press, 1995, p. 1. 3 A.
