Abstract
This chapter argues that corpus linguistics has a lot to offer to research and practice in Second Language Acquisition (SLA), especially if different methods and data types are combined in a “methodological pluralism” sense (McEnery & Hardie 2012: 227). The chapter also suggests that progress in corpus-based SLA research will depend to some extent on successful collaborations between corpus linguists and scholars from related fields. After a brief overview of some existing uses of corpora in SLA, the chapter will present findings from two case studies that benefited from mixing methods and from the author’s collaboration with researchers from neighbouring disciplines.
