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.
