Abstract
This study analyses and discusses the pragmatical negation in selected U.S and Nigerian presidential speeches. It first examined the process of speaking as a form of intimated and supportive relationship that serves as the cement that holds friendships, families, communities, societies, and government together. The focus is on political discourse which is closely related to power, that puts certain political-economic, and social ideas into practice. Text of acceptance and inauguration speeches of President Barak Obama of the U.S.A and President Goodluck Jonathan of Nigeria is selected to be the working data. Three components, Description, Interpretation, and Explanation were used as the bases for analysis and discussions.
