This book explores the ways in which language is understood in diverse contexts, and how linguistic theories – and the idea of language as an object – fail to represent a reality that is inherently multi- and trans-. The chapters tease out the way that an understanding of language as a social practice, and the central role of the speaker(s) and their repertoire, allows for a more nuanced interpretation of language in contexts ranging from English as an international ‘neutral’ language in research and teaching, to the importance of life trajectories and multilingualism in the development of theoretical perspectives. The book offers a glimpse of a decolonial linguistics that recognizes the importance of entanglement – between languages, between the North and South and between the personal and the theoretical.
