Because the language has been incorporated into the traditions, religions, philosophy and so many other things of a target culture, understanding the culture of the language can be very helpful to learn and use the language better. In a target culture, the language ties everything together. The language has lived for so long that many aspects of the culture, the civilization, traditions, and religion, rely on the language to be passed on from generation to generation. For example, when I was learning Japanese, the understanding of the Japanese hierarchical culture helped a lot on distinguishing which degree of politeness and intimacy should I apply in language when I’m talking to different people. Messing up with addressing people can be very rude and weird in Japan, even as a non-native language learner.
At the same time, the language changes and adapts to the changes in the target culture. The understanding of the culture, especially the pop culture, can be very helpful in improving speaking the language. Many people, including me, enjoy watching Japanese animes, TV shows, and variety shows because we can learn those slangs and trendy expressions. Usually, we learn the language through textbooks that have very formal expression and word. But often, in daily life, there are words and phrases that the textbooks don’t have. Instead, we need to learn the culture of the language, what’s new recently, what happened so that people started using certain words than others, etc.
The understanding of the culture can be considered as the tool to improve the communicative competence. In the textbook, I can learn how to be organizational competence in Japanese. I learn the grammar, vocabularies, syntax, phonology, and graphology. I know how to read the text, to interpret and understand the meaning of the text cohesively by studying the textbook. This seems like the beginner’s stage, the basic and foundation of learning Japanese. It’s more about absorbing and input of all the knowledge of the language itself. This is very important for learning a language because as learners, not like people born with Japanese, I would not know the construction, or how to construct Japanese. I have a friend who never learns Japanese systematically but always watch the Japanese animes. He can totally understand Japanese by hearing it. But he can’t read or write Japanese because he doesn’t have the organizational competence. Instead, he has some degree of pragmatic competence of Japanese because he could understand it by watching people talk and behave. However, of course, pragmatic competence cannot be greatly improved without the foundation, the grammar, etc of the language.
Thus, if I want to improve my pragmatic competence of Japanese, I should watch more Japanese TVs, read more newspapers, magazines, and talk to Japanese in Japanese. I should learn the Japanese culture so that I could produce my own output of the language. I could speak more fluently by manipulating the grammar, using the words and phrases that are popular among people in the present. I could use the address more accurately. I could better comprehend Japanese conversations, implying meanings, even dialects. In summary, I could be not only academically knowing Japanese but socially, by learning the culture. To me, the pragmatic competence is more about socially integrating with the language, and thus, the understanding of the culture of the language is necessary and essential.
