Proper knowledge of language is necessary.Many people do not even properly know their own language. Speaking and acquiring knowledge of the language are both different things. There is no need to become a very big linguist, but your colloquial language should be decent and pure. Language knowledge is very important. If you go somewhere in the country and abroad to work or work, then the language is very much with you. A good communication process with language can only happen when you have learned to think well. It is also necessary to increase the word knowledge to be thoughtful.
