Introducing Diza, a 10-year-old girl living in Nyanjida. Her parents primarily self-identify as Vute speakers, although of different mutually intelligible dialects. She begins her day at her mother’s house, greeting her family in Vute before spending the day with her grandparents, a common practice for language and sociocultural transmission. They possess individualized, asymmetric repertoires, each comprised of at least 5 languages. Diza’s grandmother is Gbaya, from another village; she will converse in Gbaya while her Vute husband responds in Vute, practicing receptive multilingualism. Diza will use both languages in conversation. Her grandmother may send her on an errand to a nearby Fulfulde-speaking village, where she will speak a more formal register of Fulfulde, different from the Fulfulde register she uses with nomadic Fulfulde speakers. On her way, she will pass through a Gbaya village, greeting people in several languages, with attention to formal and informal registers. She attends school, with French as the strictly enforced language of instruction. On the playground, she listens and converses in a variety of languages with varying typological proximities, dialects, and registers. In the village, Diza plays an interstitial role between older and younger speakers; her social responsibilities equip her with a diverse linguistic repertoire comprised of not only her dialects of Vute, Gbaya, and Fulfulde, but also a continuum of dialects and registers in those languages through exposure to a wide-ranging social network. Diza also spends time in her father’s village, where she is exposed to various other Vute dialects and linguistic ecology. She and her four siblings each have very individual repertoires dependent on having different fathers and relatives with distinct repertoires, and in conversations with each other will access features from all languages in their repertoires.
