This chapter discusses the experience of designing and teaching a core undergraduate course in English linguistics with a World Englishes perspective. Inspired by Kumaravadivelu’s postmethod pedagogic principles and by scholarship challenging the monoglossic ideology and racialised logics on which English language education is rooted, the course aims at introducing the fundamentals of English morphology and word-formation while promoting an inclusive, egalitarian, and decolonial view of the English language. Lessons are organised in three teaching blocks and follow a four-step procedure that ensures a balance between frontal teaching, discussion, practice, and reflection. The teaching material includes a range of texts and videos presenting examples of standard and innovative word-formation patterns in several varieties of English (sample material is available in the Support Material section online). The contents and structure of this course are designed to enable students in higher education to develop non-adversarial attitudes towards speakers from any region of the Anglosphere and to promote a higher degree of ownership of the English language. The chapter concludes with a lesson plan with suggested activities and references for teaching a themed class on innovative word-formation in Indian English.
