Why is Language Important to Understanding a Culture?

For the linguist Edward Sapir, language is not only a vehicle for the expression of thoughts, perceptions, sentiments, and values characteristic of a community; it also represents a fundamental expression of social identity. Sapir said: “the mere fact of a common speech serves as a peculiar potent symbol of the social solidarity of those who speak the language.” In short, language retention helps maintain feelings of cultural kinship.
