Taking the theories of classical rhetoric as a starting point, we deal with inventio, dispositio, elocutio, memory and actio, common in every communicative act, and we will focus on two essential elements of persuasive rhetoric: one that is related to elocutio, that is, the selected vocabulary that determines the intention that the source has at the time of making the speech, and the other related to the inventio, that is, the type of discourse selected: the story or the narration as a format in which the discourse is framed to reach the recipient with the least amount of effort, and the greatest possible effectiveness. So, from this approach, we will study the word and the “mold” through which the discourse arrives to obtain an emotional response in the recipients.
