Mastering vocabulary is an ability to get or to receive a lot of words. By having and mastering vocabulary, they will know the meaning of
vocabulary in the content. It also helps students avoid making the mistakes in identifying a vocabulary with the dictionary and as guidance in making
the equivalence of the target language. Here are some of vocabulary uses:
a. Distributing the words according to grammatical matters
If students examine vocabulary use, there are so many useful things, especially its distribution to grammar matters. Such the words, although
some of them may have also full word meaning content, primarily or largely operate as means of expressing relation of grammatical structure. This
includes the so-called auxiliaries, prepositions, conjunctions, interrogative particles, and miscellaneous group consisting of the words for degree for
generalizing, the articles, etc.
12
All of these words are called as function words or the words have special function and meaning.
Auxiliaries, helping, or supporting words include words that can help in making various form and inflection of the verb and absolutely serve
certain meaning or function, such as, using can, could, may, might to express the ability and a polite request or permission. Should and ought to,
to express the advisability, moral obligation, duty and expectancy and shall to express a request for agreement or an offer to do something for someone.
Preposition-adverbs, the function words used with substantives that used a noun or pronoun include the nine already indicated as being most
frequently used, “at, by, for, from, in, into, of, on, to, and with” but also
some twenty others that express grammatical relationships in situation such as; behind, in front of, over, under, above, below, beside, between, beyond,
and around to indicate the place, through, into, out of, toward, away from, up, down and across to indicate the direction, before, after, during, since,

and until to indicate the time, for, because, and since to indicate the cause, in order that, so that, to indicate the purpose, although to indicate the
comparison, unless and whether to indicate the condition and therefore to indicate the conclusion.
The function words are the interrogative particles who, whose, which, what, where, why and how. The articles the, a, an. Degree words more,
most. The generalizing particle ever. Special uses there, it, and one.

From the explanations above, it is clear that the vocabulary is really useful and important to improve students’ grammar because by knowing the
function words and various types of words, students will find and get the suitable meaning of the native language.
