Chapter 6. Documenting interlanguage development
This chapter illustrates Selinker’s (1972) claim that interlanguage is a linguistic system in its own right by examining research in three different areas of L2 development: interlanguage temporality, L2 pragmatics, and conventional expressions. The chapter begins with a review of functional approaches to interlanguage analysis. It then reviews a longitudinal study of interlanguage temporality illustrating the development of form-meaning mappings as learners acquire temporal expression in L2 English. The importance of interlanguage development in the pragmatics of L2 learners is emphasized in the next section which demonstrates that the interpretation of learner forms in conversation is dependent on the inventory of available linguistic devices. The chapter closes by considering the role of interlanguage grammar in the production of formulaic expressions.
