Language In Social Life

I live in social life, so I do need to communicate one another. I can not be separated with language and as we known language used in social life as a sociolinguistic. I found several kind of languages in social life and I must be able to speak in those languages in order to communicate.
In this case I notice something interesting in using some language in communication. These are “Code Mixing” and “Code Switching”.
Code Mixing is some technique in using language to communicate in order to make the interlocutor get more understand what I am saying; when I mix or combine two or more different languages while I am speaking. I often use it either in formal or informal. For example I use it in formal occasion while I am delivering material in some presentation. I mix/ combine English and Indonesian language. I use Code mixing to overcome limitation of vocabulary, because sometime I can not find some words in English (E.g. : enlarge). So I use the Indonesian words (E. g. : memperluas) to over come. I speak English and then I put some Indonesian words in my speech. What I am doing is to keep the interlocutor understand what I am talking about. In in-formal occasion I also use the code mixing. For example when I am chatting each other to talk about a lesson talking in Javanese and then I put some words in language outside Javanese. I use the term “it’s gonna be easy” to emphasize the meaning that I want to convey, but the interlocutor still understanding what I am saying. It is also make it more associable (gaul) to keep my existence in community.
While Code Switching is I switch some language into another language totally. For example when I am at campus where people come from everywhere (western, Jakarta, local people); they speak in different language also. When I talk to the local people I always talk in Javanese. Then if want to talk people come from Jakarta who are not able to speak in Javanese, I have to use Indonesian language to make them understand. Then when I speak to western people I must use English and not use neither Javanese nor Indonesian anymore; in order to keep the interlocutor understand what I am talking about.
