2.1. Bilingualism
In  this  world,  language  is  a  necessary  for  human  communication. Human needs a language to do a communication with others. According to
Jendra  Jendra,  2010,  p.  1 language  is  used  only  to  human’s  way  of
communication.  It  means  that  human  cannot  communicate  with  another without  language.  So,  it  must  be  difficult  for  human  to  interact  with
another.Language will be useless when it is not applied or used by human in  their  society.Thus,  it  indicates  that  language  and  society  is
complementary to each other. It is as what Janet Holmes Holmes, 2013, p. 1  states  that  sociolinguistic  is  the  study  of  the  relationship  between
language and society.
