Indonesia has so many ethnic groups whose languages are different from each other. There are some big
ethnic groups; Javanese, Sundanese, and etc. Here, in this case, the writer only focuses on one of Indonesia’s
ethnics and languages that is Javanese. Javanese language is divided into old, middle, new and modern
Javanese language. The modern Javanese language is now used by most of Javanese. There are three main
dialects in the modern Javanese language; Central, Eastern, and Western Javanese. They have their own
accent and dialect that differs one Javanese language from one another. Each employs its own vocabulary
and grammatical rules. There are three Javanese language styles; Ngoko, Madya, and Krama. Those three
different styles that Javanese uses show that in Javanese there are levels of politeness. The politeness itself
is being one of a sacral thing that must be kept by every Javanese. Nowadays, Javanese language becomes
endangered language, in which at risk of falling out of use as its speakers die out or shift to speaking another
language. Most of Javanese speak in Indonesian as their national language. If they keep speaking Indonesian
in their daily communication, Javanese language will be an extinct language. The government should have
policy to protect Javanese language from being extinct by including Javanese language in school
curriculum, providing government law to force the Javanese to keep speaking Javanese language
