Inclusion in Linguistics, the companion volume to Decolonizing Linguistics, aims to reinvent linguistics as a space of belonging across race, gender, class, disability, geographic region, and more. Taken together, the two volumes are the first comprehensive, action-oriented, book-length discussions of how to advance social justice in all aspects of the discipline. The volume's introduction theorizes inclusion as fundamental to social justice and describes the extensive dialogic and collaborative process through which the volume was developed. Contributors discuss intersectional forms of exclusion in linguistics: researchers' anti-autistic ableism; the exclusion of Deaf Global South researchers of color; the marginalization of Filipino American students and scholars; disciplinary transphobia; and the need for a big tent linguistics. The volume goes on to outline intersectional forms of exclusion in linguistics, describes institutional steps toward inclusion, offers examples of how to further educational justice, and shares models of collaborations designed to create an inclusive public-facing linguistics. The volume's conclusion outlines actions that linguists can take through research, teaching, and institutional structures to advance inclusion in linguistics and move the field toward social justice.
