This book focuses on creative subtitling - otherwise known as 'text-on-screen' - through the lens of relevance theory, a cognitively grounded theory of communication. Sasamoto explores the ways in which a relevance theoretic approach can provide an analytical framework for a better understanding of the interaction between 'text-on-screen' and viewers' interpretation processes and, in turn, how media producers, professional or otherwise, use 'text-on-screen' to engage viewers in innovative ways.
