It is normal in Nigeria to use proficiency in the use of English language as a barometer for evaluating the height of any person's educational attainment. Today, many teachers resort quite often to the use of vernacular in the teaching of their subjects. One is often dismayed at the incompetence of many teachers, even graduates in the use of English language. Throughout the colonial period, up to 1960, Nigerian formal education was patterned after the English system. The "accent" was on English and an educated Nigerian was one who was only African in colour but English in thought and culture. The ability to speak English fluently and if possible with an Oxford accent was the hallmark of excellence even if the speaker was empty of thought and ideas. In those days it was a serious offence for a secondary school boy or girl to "laugh in the vernacular". But we now swung to the other extreme. Nigeria would say they are not English people, some would say they did not specialise in English in the university. But the country has adopted the English language as its official, the language of instruction at schools, parliamentary proceedings, conduct of official business and indeed the lingua franca. If the language is to continue to be used,  then it is imperative that we all agree on the pattern of correctness in the language so that communication can be effective.
