The main purpose of this research is to draw insights from Nigeria to find out how language serves as the key to global research and challenges in the 21 st century. This research is necessitated by the fact that apart from the point that globalization will be very difficult if not impossible without language, language is also a major tool to fix every challenge of life since solution to problems of life arises through thought. The researcher draws her data from bill boards, television, posters, and other secondary sources of data like textbooks, journals, internet, etc. and adopts a descriptive framework for the analysis of data. The investigation portrays the fact that language is an indispensable tool not only for global research but for resolving all the challenges facing Nigerians in the 21 st century. The study shows that there are challenges in the health, security, educational, social, economic, and political sectors in Nigeria. It equally reveals that through language, solution to the health, security, educational, social, economic, and political challenges in Nigeria is provided. 展开更多
