The Significance of the Study
without words to express a wide range of meanings, communication just cannot happen in any meaningful way.

It means that understanding a large number of vocabulary will be helpful for language learner better than
understanding language structures and sound of language because by learning vocabulary learners will be able to understand the language.
Moreover, as Kreshen points out that a large vocabulary is very crucial for mastering a language.
15
It means that vocabulary is the key to students for understanding what they hear and read in the school; and then communicating
successfully with other people. As Wilkins emphasizes the importance of vocabulary acquisition in learning language by stating that without grammar
students cannot make communication but without vocabulary it is impossible to communicate with other people.

From the explanation above, it showed that vocabulary is important for the students in teaching learning process. If the students just have a little of
vocabulary, they will be unable to understand the question and the text of English. In addition, if the learners have lack of vocabulary, they do not have
very much information or knowledge. Otherwise, if the students know and understand vocabulary they will be able to communicate effectively and
understand the English text.
