Language is the principal tool of the politician and as such offers much in the way of linguistic analysis for the study of the power of lexis and syntax to persuade and motivate. From the specific words required for wartime, to the promotion of a political agenda or the need to expose injustice, speeches employ the many and various linguistic devices within their textual structure to argue and persuade effectively. Language is a powerful and emotive stimulant, dangerous in the hands of a skilled orator with an ambivalent or perilous personal agenda. Certainly, the way a speech is constructed and delivered has been shown over the centuries to have tremendous influence, both negative and positive, and knowledge of method and intent are important in the ability of an audience to differentiate astutely between the two and avoid being either persuaded or motivated against their better interests or those of the public at large. Thus, understanding the nature of persuasive and motivational argument is essential in order for the listener to make informed, rather than merely linguistically manipulated, choices based upon skilful speech.
