Language is more than a tool, this fact we know and much recognized by all literate man. We devote significant amount of our life to the study of language, because it carries our tradition, our history, our thinking, our ideas for the future. Man in his life ideally should study not only his mother tongue, English, and another language. It is part of our life. It is art.
