This ethnographic case study explores the factors that add to multilingual choices and identities' construction in a linguistically diverse family within a linguistically diverse city, Dubai in the United Arab Emirates (UAE). Based on interviews with a female Emirati in her early thirties, the paper explores this young woman’s dispositions (habitus), beliefs and practices with regard to the language and literacy resources at her disposal. It describes how she considers English and diverse varieties of Arabic, centering mainly on her language practices, and their role in the construction and management of her identities, within personal and professional relationships and in relation to the various tasks that she executes in daily life. The study shows that in this superdiverse society, existing language ideologies, indexicalities, stereotypes, and gender issues, may make multilingualism performance and identities' construction potentially gratifying but also potentially bothering, especially for those individuals who, through birth and/or marriage, are members of several national or ethnic communities, and who may be, in some senses, icons of superdiversity.
