Intralingual Translation: Beyond language and text offers an innovative, wide-ranging exploration of translation within the same language, bringing together leading international scholars from diverse linguistic and disciplinary backgrounds. Spanning theoretical reflections, empirical studies, and historical analyses, the volume addresses the rich spectrum of intralingual practices, from plain language and accessibility adaptations to diachronic rewritings of historical texts. The first section investigates various aspects of the “Intralingual Sphere” and its connections to other modes of translation. The second part explores the rapidly developing field of accessibility and simplification, including Easy Language, plain language, and graded readers. The book concludes with in-depth studies of diachronic translation across different historical layers of the French, Italian and Latin languages. Originating in an international workshop, these contributions highlight intralingual translation as a multi-faceted and socially situated activity, offering new insights into its theoretical boundaries, practical challenges, and cultural significance.
