Based on the Discourse Space Theory, this research sought to analyze the deictics used in the political discourse. Drawing on three speeches of the American President Donald Trump, this research explored the types of deictics and the frequency of using each type in each of the three speeches. To achieve this purpose, qualitative and quantitative analyses were conducted. The AntConc 3.5.0w was used to calculate the frequency of using each deictic type. Then, the percentage and the number of each deixis per 1000 words were calculated to facilitate comparison between the frequency of using each type of deixis in Trump's three speeches. The results indicated that Trump employed different types of deixis including the personal, temporal, spatial, discourse and social deixis. However, the frequency of using each type varied from one speech to another. It was observed that the audiences influenced Trump's use of deixis. Finally, the elements of the space in each speech could be defined. People, entities and events were located on different positions on the spatial, temporal and modality axes of the Discourse Space Theory.
