ABSTRACT
Linguistics has impacted research in second language acquisition since the early days of SLA research, with virtually every theory of linguistics having had some relevance to SLA research. In this chapter, we focus our discussion of that relationship on the area of research that has dominated the theoretical study of second language acquisition over the years, Universal Grammar. This area of research is dealt with in this chapter along with issues of phonology; typological universals are discussed in chapter 7.
