Romani is a diaspora language par excellence as it is an Indic language spoken exclusively outside the Indian subcontinent, namely in Europe, the Americas, and Australia. Over the centuries, some Romani varieties ceased to be transmitted to younger generations (mainly in northern and western Europe), while others were maintained (mainly in the Balkans, central and eastern Europe, and in the Americas). All, however, were shaped by extensive multilingual practices with various European languages. In the first part of the article, I present an overview of the contact-induced changes noted in different Romani varieties. In the second part, I discuss dispositions as expressed by Roma from Romania and Colombia in two surveys. In both surveys, respondents are in favor of the intergenerational transmission of Romani at home along with the language most relevant in work-related interactions. In sum, Romani offers a unique opportunity to observe how multilingualism allows a language to be maintained in some diaspora settings, while changing to converge with the contact languages, but also how in other settings multilingualism leads to language shift.
