With the developing of a certain language,a certain culture would eventually take place around.And once the culture was formed,it would direct the way according to which the later language would develop,along with the culture evolves itself.Hence though culture is quite abstract and vague,it can be reflected by language,by the communication for which the certain tongue serves.The cultures root in different languages would turn out to be different from each other,which could be told when studying the language of it.
All in all,where there is language,there is communication,from which we can see the distinct cultures that symbolize the variety of nationalities.
