2.1.1.1 Vocabulary Knowledge
Vocabulary knowledge means the knowledge in which the learners learn about the words, meaning of words, and how to use the words in the sentences
when somebody is learning English, especially English as a foreign language. According to Young 2007, vocabulary is a study of the word meanings, how to
use the words, and root words and the affixes. In other words, vocabulary does not only learn about the meaning of the words, but also the use of the words in
different context. The students need to realize that vocabulary is an index of the nature and quality of their lives. Words can reflect what they have studied Dale
and O’Rourke, 1971: 9. The people who are learning vocabulary have strong relation with the
reading comprehension Lehr, 2001. The learners get more knowledge of vocabulary from many reading materials. The learners should read many kinds of
readings in different difficulty level. By reading a lot of different level in words’ difficulty, the learners will have more understanding of the meaning of words and
their function in different context. Reading is not only one of the English skills that can help the learners in improving their knowledge of vocabulary. Through
listening to many passages, the learners can also learn many words and the meanings. In learning vocabulary, there are words families and core meaning.
When the learners are learning a foreign language, such as English, they will learn word families and core meaning. According to Nunan 2003 word
families are the basic words added by plural form, present tense, past tense, etc. for example: the word “fan” become “fan, fans” and “walk” become “walk, walks,
walking, walked”. Core meaning is also important for the learners in learning English as a foreign language. It can reduce the number of items the learner has to
cope with, provide access to a wide range of uses, and often contrasts with the first language of the learners.
2.1.1.2 What Is Vocabulary?
According to Young 2007, vocabulary is the study of the meaning of words; how words are used; root words, prefixes, and suffixes; and analogies. In
learning vocabulary, the learners study the several different meanings of words and the part of speech. The learners also learn how to use the words. It means that
the learners study the words in the context and apply what they learn in the form of writing. Words have their own roots and affixes. The learners will study root
words and affixes that can support their vocabulary learning. They get more knowledge about original words and the other forms of the words. Analogy is
comparing two pair words and choosing the pairs that go together. There is an example of learning vocabulary by analogy.
