Language changes with time and context. What is your opinion about what constitutes good or bad usage? Is it necessary for speakers or writers to follow a particular standard of correctness? Do such standards vary with the audience and the situation? Do you think an individual or a group of individuals can actually maintain a certain quality of language and usage? If your answer is yes, state how these rules can be applied effectively. If your answer is no, then state the reasons why such control should not be exercised. Write a short essay to state your position on these questions.
