Abstract: Vocabulary is considered as the heart of language comprehension, and learning English vocabulary is an important component for all students because nothing can be conveyed without vocabulary in English communication. On the other hand, a great deal of research has recently been conducted to deal with vocabulary learning. Based on pre-research, it is found out that high school students had problems in mastering vocabulary, especially vocabulary acquisition because it requires students’ capacity not only to perceive but also to use words to understand and communicate.
