The purpose of using two or more languages in communication is to build good communication based on social factors.

The theories used in this research are by Bloom and Gumperz (1972) about types of code-switching, Hoffman (1991) about reasons why people did code-switching, and surface strategy taxonomy by Dulay et al (1982) about types of error.
