This study aimed to investigate the existence of ideology in the discourse of the Islamic State of Iraq and Syria (ISIS) by examining the linguistic elements of two speeches through video addressing Jordanians. The discourse analysis approaches were adopted, such as the socio-cognitive and ideology theories of Van Dijk, which were considered to sense the manipulation of discourse and find out ISIS's discursive strategies. The study analysed two videos broadcasted on the Internet and social network accounts at a superstructural level, namely, the context, pattern, and topic which uncovered that ISIS carefully took into consideration the political and social context of Jordan to elaborate speeches exploiting Islamic topics and practices familiarly and persuasively. The study concluded that the discursive strategies of ISIS were constructed by glorifying the group members' actions and achievements while de-emphasising the outside group's positivity and delegitimising its authority.
