This aims to examine intralingual translation from every possible angle. The introduction gives an overview of the theoretical, political, and ideological issues involved and is followed by the first section which investigates intralingual translation from a diachronic perspective covering the modernization of classical texts. Subsequent sections consider different dialects and registers and intralingual translation from one language mode to another, explore concepts such as self-translating, transediting, and the role of copyeditors, and investigate the increasing interest in the role of intralingual translation and second language learning. Final sections examine recent developments in intralingual translation such as the subtitling of speech for the hard-of-hearing, simultaneous Easy Language interpreting, and respeaking in parliamentary debates. By providing an in-depth study on intralingual translation, the sheds light on other important areas of translation that are often bypassed, including publishing practices, authorship, and ideological constraints. Authored by a range of established and new voices in the field, this is the essential guide to intralingual translation for advanced students and researchers of translation studies.
