This chapter examines the consolidation of attitudes and praxis in relation to the emergence of a supraregional accent of English. Engaging in detail with phonological history, it documents the increased salience of delocalisation in representations of speech from the mid eighteenth century onwards while exploring the intersection between formal prescription and private practice. An abundance of primary texts on the need for a normative model of speech was in existence by the late nineteenth century while popular culture, and an emerging national system, also addressed desiderata of this kind. The advent of the pronouncing dictionary, an influential sub-genre in the history of lexicography, is a further important strand in the attempted dissemination of one accent for all, though broadcast English brought other avenues by which paradigms of ‘received’ English were both implemented and encouraged. If the social, cultural and linguistic hegemonies of a ‘standard’ accent were originally embedded in formally democratic models, the chapter also provides a critical examination of both the rhetoric and praxis of ‘received’ English in this respect, alongside its legacies in Present-Day English.
