English as a lingua franca: between form and function

In this paper I wish to discuss some aspects of the current debates about the concept of English as a lingua franca. In doing so, I will use a recount of the pre-publication stages of the volume English in the World: Global Rules, Global Roles, co-edited by Rani Rubdy and myself (2006) as a starting point, to set the scene, and will move to more theoretical considerations in the second part of the paper.
