In a corpus compiled from the notes in John Walker's pronouncing dictionary (first edition 1791), Trapateau (2016) found that the most frequently occurring evaluative term used was vulgar. In Walker's dictionary, vulgar is defined as ‘plebeian, suiting to the common people, practised among the common people, mean, low, being of the common rate; publick, commonly bruited’ (1791, s.v. vulgar). The frequency of this term in Walker's critical notes suggests that the role of his dictionary was to warn against unacceptable pronunciations as well as to provide an account of acceptable or, to use Walker's second most frequent term, polite ones. In this article, I discuss some of the pronunciations labelled vulgar by Walker and other eighteenth-century authors and argue that, far from dismissing such evidence as prescriptive, we should consider the role played by Walker and his contemporaries in the enregisterment of stigmatised variants and varieties.

Yod-coalescence involving alveolar consonants before Late Modern English /uː/ from earlier /iu > juː/ is still variable and diffusing in Present-day English. For example, the Oxford English Dictionary (OED) gives both (/tj dj/) and (/ʧ ʤ/) British English pronunciations for tune (/tjuːn/, /tʃuːn/), mature (/mǝˈtjʊǝ/, /mǝˈʧʊǝ/), duke (/djuːk/, /dʒuːk/) and endure (/ᵻnˈdjʊə/, /ɛnˈdjʊə/, /ᵻnˈdʒʊə/, /ɛnˈdʒʊə/, /ᵻnˈdjɔː/, /ɛnˈdjɔː/, /ᵻnˈdʒɔː/, /ɛnˈdʒɔː/). Extensive variability in yod-coalescence and yod-dropping is not recent in origin, and we can already detect relevant patterns in the eighteenth century from the evidence of a range of pronouncing dictionaries. Beal (1996, 1999) notes a tendency for northern English and Scottish authors to be more conservative with regard to yod-coalescence. She concludes that we require ‘a comprehensive survey of the many pronouncing dictionaries and other works on pronunciation’ (1996: 379) to gain more insight into the historical variation patterns underlying Present-day English.

This article presents some results from such a ‘comprehensive survey’: the Eighteenth-Century English Phonology Database (ECEP). Transcriptions of all relevant words located are compared across a range of eighteenth-century sources in order to determine the chronology of yod-coalescence and yod-dropping as well as internal (e.g. stress, phoneme type, presence of a following /r/) and external (e.g. prescriptive, geographical, social) motivations for these developments.

This article presents the Eighteenth-Century English Phonology Database (ECEP) in the context of historical phonology and historical corpora. The eighteenth century witnessed the proliferation of works on elocution and orthoepy and yet the field lacks searchable digital sources comparable to those available in other disciplines like historical syntax or historical pragmatics. Because of this and for other reasons such as the difficulty in deciphering idiosyncratic notation systems in the original materials, there has been a certain disregard for the study of eighteenth-century phonological evidence. The ECEP database aims to redress this absence of research material by collecting data from eighteenth-century pronouncing dictionaries in the form of IPA transcriptions (c. 1,600 different example words totalling c. 17,600 transcriptions) and supplementary metadata, with a view to facilitating systematic analyses of phonological, chronological and geographic patterns, and also normative attitudes. The richness of the contents in ECEP will thus be of interest to phonologists, dialectologists and language variationists from the historical as well as the synchronic perspective, in that eighteenth-century orthoepists laid the ground for what became ‘Received Pronunciation’. Methodologically, the compilation of the ECEP database aims to contribute to the thriving field of corpus linguistics with a new research tool for the study of the history of English.
