This book offers a comprehensive examination of linguistic intensification in Spanish and English communication. It explores how it is defined and the various linguistic features, strategies, and devices we employ to escalate and amplify our oral and written communication. The book builds on a body of literature concerned with linguistic intensification, and it begins by discussing how scholars have conceptualized it as a socio-pragmatic phenomenon. It also accounts for this phenomenon using Persuasion Theory, and it exemplifies how speakers and writers often escalate in various discourses to sway and persuade audiences. The main goal of the book is to increase our awareness of intensification. It also aims to unpack ways to teach language learners how native speakers amplify the illocution of their communication. Finally, we seek to reach out to linguists, graduates, young scholars, researchers, and language teaching professionals by inspiring all to examine and expand on intensification in communication.
