This chapter is the result of a conversation between Professors Tony McEnery and Michael McCarthy, two of the greatest names in the fields of corpus linguistics and the corpus-based analysis and teaching of the English language. They share their views and experiences of the areas discussed in this volume, including the relationship between DDL and SLA research, the role of formulaic language, spoken language and pragmatics as areas of potential applications of learner corpus research (LCR) methods, the role of frequency in language learning and teaching and, among others, annotation.
