Summary: | Multidisciplinary and interdisciplinary theorists have recently begun to take an interest in the political economy of language, specifically with a concern for the impact of English as a global lingua franca. Political, linguistic, educational, and economic researchers interested in the political economy of the English language should remain aware that the diverse disciplines often lack a common language and that it can be easy to misconstrue interpretations of the political implications of linguistic globalisation. In doing so, the research area needs to develop a theoretical base that provides greater depth-of-knowledge. Thus, following a critical review of the most influential work in the area, the purpose of this article is to provide a knowledge map through a theory-based method grounded in a history of ideas.
