Language experts or educationists in time past had advocated for the usage of Nigerian "pidgin" in teaching. This was thinking of the National【M5】 Commission for Mass Literacy Adult and Non Formal Education in 1992 which was introduced to produce literacy materials in Nigeria "pidgin". Unfortunately the project has since been suspended on.【M6】 It is not uncommon to find parents teaching or communicating in English with their children without recourse to the necessity of first bequeathing their native languages to them. This imported city practice(s)has spread colossal to different parts of Nigeria. But【M7】 the parent must ensure that the child as a matter of priority UNDERSTANDS the mother tongue and SPEAKS it, after they(may)【M8】 decide to change the code and educate him or her on the other. Civilization does not presuppose the abandonment of culture or his【M9】 language, rather it requires an integrative approach in which such local languages are developed via to the instrumentalities of communication【M10】 in our day-to-day existence.
