This study was carried out to find out the role of Nigerian pidgin English. The Nigerian Pidgin English is a type of English used and understood by so many people in Nigeria regardless of ethnic, cultural, and socio-economic background. Even though some people now use it in social communication, pidgin English is not only used in places like market local community and so on, but also Nigerian secondary and tertiary institutions’ students now use pidgin English to communicate with each other. The continued use of Pidgin English in Nigeria made the number of interest of its speakers to continue to expand and this encouraged the growth of Nigerian pidgin. Therefore, this project attempts to study the role of Nigerian Pidgin English especially in Army Day Secondary School, Sokoto.
