Vocabulary is one of the most obvious components of language and one of the first things applied linguists turned their attention to. Vocabulary is list of words with their meanings, especially in a book for learning a foreign language (Richard, 2002:4). According to Nunan (1991:101) Vocabulary is more than lists of target language word. Based on the definition above it can conclude that vocabulary is intimately interrelated in grammar. In fact, it is possible to divide the lexical system of most language into grammatical word.
Teachers know they must do something with the language of their content areas and provides much of the basis for how well learners speak, listen, read and write. It is also stated that “vocabulary is the total of words in a language”. Vocabulary includes of words that are used in communication through language, whether using language in the manner of spoken or written (Djiwandono, 1996:42). It can be inferred that vocabulary is the total of words in a language.
Advanced learners can generally communicate well, having learnt all the basic structure of the language. However, they need to broaden their vocabulary to express themselves more clearly and appropriately in a wide range of situations. The students might even have receptive knowledge of wider range of vocabulary, which means they can recognize the item and recognize its meaning. Nevertheless, their productive use of a wide range of vocabulary is normally limited and this is one of the areas that greater attention.
Vocabulary study seems consistently to revolve around the dull routines of looking up defining and memorizing words and using them in sentences. Although there was nothing inherently wrong with looking up, defining and memorizing words and using them in sentences, the approach itself is too narrow for users to learn words in depth. Instead, learners memorize definitions to pass the Friday quiz and forgot them on Saturday.
Having students learn lists of words is based on the ill-founded conclusion that the acquisition of vocabulary is separated from the development of ideas and concepts in a content area. Teaching vocabulary often means assigning a corpus of words rather than exploring words meanings and relationships that contribute the student’s conceptual awareness and understanding of a subject. Once teacher’s clarity the relationship between words and concepts, they are receptive to instructional alternatives.
One classification involves the three types of reading vocabulary found in textbooks (Richard, 1999:314);
The first type general vocabulary, it consists of everyday words with widely acknowledge meanings in common usage.
The second type, special vocabulary, it is made of words from everyday vocabulary that take on specialized meanings in a particular content area.
The third type, technical vocabulary, it consists of words that are used only in a particular area.
According to Harmer, there are two kinds of vocabulary (Harmer, 1991:159):
a. Active vocabulary
Active vocabulary is used in oral and written expression by the students. The words that the students understand well enough they use the words effectively in both speaking and writing. b. Passive vocabulary
Passive vocabulary is deals with words the students will recognize understand in a context that helps them recall the word meaning. The students usually apply passive vocabulary in listening and reading materials.
From the explanation above, the types of vocabulary can be classified into two these are active and passive vocabulary. Active vocabulary used in speaking and writing skills. Then passive vocabulary used in listening and reading skills. a) Kinds of Vocabulary Topics for Elementary School
