Nurenzia Yannuar is a lecturer at Universitas Negeri Malang, Indonesia. She completed her PhD at Leiden University Centre for Linguistics (LUCL) in October 2019. Her doctoral research was on the structure and development of Bòsò Walikan Malangan (‘Malang-style reversal language’), a word-reversal practice in the East Javanese variety of Malang. The monograph can be downloaded here. She was affiliated as a post-doc fellow to Dr. Tom Hoogervorst’s NWO/VENI project ‘The language of popular culture’, at KITLV. Their project explores the sociolinguistics of plurilingualism that are used in Tjamboek Berdoeri’s Indonesia dalem Api dan Bara ‘Indonesia in Fire and Embers’. Set in the 1940s, the novel gives unique insights in the dynamic language ecology of pre-independence Indonesia, which were rarely written down in such detail.
