The correct answer to this open question is the following.
In France, a committee exists which has the job of eliminating subversive foreign influences in the form of words borrowed from other languages. English is a major offender (as in le bluejeans or le hamburger). This is an example of linguistic nationalism.
Countries such as France uses linguistic nationalism to support their own language, culture, customs, and tradition. They do not like to be affected by linguistic imperialism, where dominant foreigner countries try to use language as a form or influence on other nations. Linguistic nationalism promotes the language of the nation to strengthen the patriotic sense of pride in one's nation.
