The Importance of Teaching Vocabulary Vocabulary is one basic component to develop English as a foreign language at elementary, intermediate, or advance levels. It plays important roles to support other language skills such as listening, speaking reading, and writing. Coady and Huckin state “vocabulary is central to language and of critical importance to the typical language learner.” (Coady and Huckin, 1997:5) McCarthy has a statement about the importance of vocabulary, he states “No matter how well the students learns grammar , no matter how successfully the sounds of L2 are mastered , without words to express a wider range of meaning, communication in L2 just cannot happen in any meaningful way. (McCarthy, 1990: iii) Rivers in Nunan says that the acquisition of an adequate vocabulary is essential for successful second language use because without an extensive vocabulary, we will be unable to use the structures and functions that we may have learned for comprehensible communication.(Rivers in Nunan, 1991: 117) From the opinion above, it can be concluded that vocabulary is very important to achieve language skills as listening, reading, speaking and writing
