Language is everywhere, and we need it in almost everything. Language is used to connect, perform social actions, and provide a medium for social interactions. Language is organized and collaborative. Whether through verbal communication or written texts, as human beings, our means to successful interaction is through language. Nonetheless, according to linguists, there are not very fine differences between spoken and written language. Researchers agree that there are no fine differences between written and spoken discourse. How about persuasive language used according to the context? Are there fine differences between the persuasive language used in both written and spoken discourse? This study aims to investigate and answer this question. When it comes to successful marketing and advertising, it is evident that language plays a big role. The aim in this paper is to analyze persuasive language in both written (non-interactional) advertising and real-life (interactional/ engaging) advertising and marketing. The researcher, in this paper, aims to study the ways in which persuasive language varies according to the context in which it is used. And whether or not the strategies of persuasive linguistics are the same between written and spoken discourse. By studying and investigating the persuasiveness of language among written advertisements (non-interactional) and spoken (real-life) selling and marketing. By comparing written and spoken advertisements and ways of linguistic persuasion in both settings or contexts, these aims are, hopefully, to be reached through studying persuasive language and persuasive language strategies in written (non-interactional) advertising and real-life (interactional/ engaging) advertising or marketing. For as they say, “Language is a powerful tool!.
