This volume brings together research on Italian and Italo-Romance varieties spoken as heritage languages across the world, with contributions from different fields of linguistics and from diverse regions (the Americas, Australia, Europe). It offers a timely update on the state of the art, combining studies on relatively well-documented communities with investigations of lesser-known groups and linguistic phenomena. A distinctive feature of the book is its search for a shared framework for studying Italo-Romance heritage language communities, namely one that takes into account the wide range of linguistic resources present in these settings. The chapters include in-depth studies of Italian and Italo-Romance heritage languages, as well as analyses of more complex repertoires, such as communities where both Italian and dialect are spoken, and onward migrant communities in Berlin and London.
