This paper tests claims concerning the English as Lingua Franca (ELF) movement's position within the world Englishes paradigm. To do so, it considers the writings of Jennifer Jenkins, a leader in this movement, on what she calls "phonological intelligibility", and the writings of Larry Smith, an established scholar on intelligibility in cross-cultural communication. The mutual intelligibility of Expanding Circle users of English is a primary concern to ELF researchers, and Jenkins has identified Smith's work as the foundation for her investigation of core phonological features to use in pronunciation teaching. The paper aims to determine the extent to which Jenkins' theoretical views on intelligibility correspond to Smith's concept of understanding as a central issue in international communication.
