THE RELATIONSHIP:
1. Language teach habits, traditions, religions and customs of their culture.
2. Language is a carrier of one's culture.
3. Every culture defines what to say, when and to whom, just as it dictates pronunciation, syntax and vocabulary.
=> I Mean if you dont understand what they hint through their language, they never succee.
