ABSTRACT
This chapter provides an overview on the traditional scholarship of different language use in language learning settings. The way languages are described during this review reflects traditional understandings of languages, namely, separate entities that exist within the user. These descriptions are seen in the use of terminology such as first language, or L1, and target language, or TL. These terms are initially used as acknowledgements of theories that have dominated language learning over the last century. By the end of the chapter, I will explain why such terminology needs to be replaced with theories of language that promote inclusiveness rather than division.
