State some rule of grammar that you have learned is the correct way to say something, but you do not generally use in speaking. For example, you may have heard that It's me is incorrect and that the correct form is It's I. Nevertheless, you always use me in such sentences; your friends do also, and in fact, It's I sounds odd to you. Write a short essay presenting arguments against someone who tells you that you are wrong. Discuss how this disagreement demonstrates the difference between descriptive and prescriptive grammars.1.

However, it's such a common expression today that everyone instinctively understands and uses it. Replying "It's I" after being asked "Who's there?" is extremely confusing and shows unnecessary slavish adherence to standard grammar. Sometimes correct English is wrong and wrong English is right. The opponents of such grammatically wrong oral expression may argue that these expressions deviate from the grammar. However, they fail to realize that there are two different kinds of grammar: descriptive grammar and prescriptive grammar. The descriptive grammar describes the rules of the language that exists in the minds of its speakers and it represents the unconscious shared linguistic knowledge or capacity of its speakers.
