The Significance of the Study
                                                                                vocabulary students could not be able to understand how the language is. The  role  of  words  is  important  to  know  how  the  language  is  used,
practiced and communicated. If we want to communicate with others in certain language we need
to  master  the  language  they  belong  to  especially  to  know  enough vocabulary of those languages. Words are the basic units of language from
that supports the language itself. Rivers quoted by Nunan has also argued that the acquisition of an
adequate  vocabulary  is  essential  for  successful  second  language  use because,  without  an  extensive  vocabulary,  we  will  be  unable  to  use  the
structures  and  functions  we  may  have  learned  for  comprehensible communication

. As  we  know,  English  is  a  „world  language’,  now  days
the  most  communication  tools  for  global  communication.  So,  we  must have a lot of „bank of English words’. Other wise grammar and exercising
pronunciation English need to be learned too. Mastery of vocabulary is an essential  component  of  all  uses  of  language;  it  helps  student  too  to
communicate effectively or expressing their ideas in English Without  an  extensive  vocabulary  and  strategies  for  acquiring  new
vocabulary,  learner  often  achieve  less  than  their  potential  and  may discouraged  from  making  use  of  language  learning  opportunities  around
them  such  as  listening  to  the  radio,  listening  to  native  speaker,  using  the language in different contexts, reading, or watching television.
According  to  Jack  C.  Richards  and  Willy  A.  Renandya, “Vocabulary  is  a  core  component  of  language  proficiency  and  provides
much of the basis for how well learners speak, listen, read, and write”.

Its means that the first thing we have to learn  English is we have to  mastery  the  vocabulary,  because  with  vocabulary  we  can  learn
Language  skill  easier  and  will  be  useful  for  the  process  of  achieving
