The spelling conventions for dental fricatives in Anglic languages (Scots and English) have a rich and complex history. However, the various – often competing – graphemic representations (<þ>, <ð>, <y> and <th>, among others) eventually settled on one digraph, <th>, for all contemporary varieties, irrespective of the phonemic distinction between /ð/ and /θ/. This single representation is odd among the languages’ fricatives, which tend to use contrasting graphemes (cf. <f> vs <v> and <s> vs <z>) to represent contrastive voicing, a sound pattern that emerged nearly a millennium ago. Close examinations of the scribal practices for English in the late medieval period, however, have shown that northern texts had begun to develop precisely this type of distinction for dental fricatives as well. Here /ð/ was predominantly represented by <y> and /θ/ by <th> (Jordan 1925; Benskin 1982). In the late fifteenth and early sixteenth centuries, this ‘Northern System’ collapsed, due to the northward spread of a London-based convention using exclusively <th> (Stenroos 2004). This article uses a rich body of corpus evidence for fifteenth-century Scots to show that, north of the North, the phonemic distinction was more clearly mirrored by spelling conventions than in any contemporary variety of English. Indeed, our data for Older Scots local documents (1375–1500) show a pattern where <y> progressively spreads into voiced contexts, while <th> recedes into voiceless ones. This system is traced back to the Old English positional preferences for <þ> and <ð> via subsequent changes in phonology, graphemic repertoire and letter shapes. An independent medieval Scots spelling norm is seen to emerge as part of a developing, proto-standard orthographic system, only to be cut short in the sixteenth century by top-down anglicisation processes.

The usual development of OE [ɑld] in words such as old in Scots is to auld, reflecting the development of this sequence in northern dialects more generally. But in some Scots dialects other pronunciations of these words, reminiscent of dialects of English south of the Ribble–Humber Line, are found. These forms, of the type owld, are found across Lowland Scotland, with particular concentrations in the far north and southwest. Origins in Irish English and English in England have been suggested for this feature of Scots but these hypotheses have not been explored. Aitken & Macafee (2002: 61–2) instead argue for an endogenous origin of both auld and owld, but this proposed double endogenous development of OE [ɑld] is problematic in a number of ways. In this article, I examine the history of these developments in Scots in comparison to their development in dialects of English in England and Ireland. The lack of evidence for the owld development in Older Scots suggests that these forms are of relatively recent origin. Crucially, the Eighteenth-Century English Phonology Database (ECEP) reveals that the owld pronunciations were in fact a feature of early forms of Standard English. Furthermore, several characteristic features of Irish English have spread into southwest Scotland, and the distribution of owld forms in the area fits this pattern. Thus Scots forms such as owld are not the result of endogenous development, but have their origin in English, in the case of southwest Scotland at least in part from Irish English, and elsewhere in Scotland from early forms of Standard English. These owld forms have been ‘localised’ and reinterpreted as ‘Scots’, alongside or replacing original auld. The analysis of the origins of this feature highlights not only the role of contact with varieties of English in the development of Scots, but also the importance of sources such as the ECEP database for understanding the historical phonology of Scots and English.

The Mouton World Atlas of Variation in English (WAVE), edited by Bernd Kortmann and Kerstin Lunkenheimer, is an impressive and significant achievement. Consisting of almost 1,000 pages of detailed accounts of morphosyntactic patterns in 55 varieties of English from around the world (with some analysis of a further 19) by an international range of experts (many of whom are native speakers of the varieties they describe), WAVE represents a major step forward in our understanding of dialect variation in English and illustrates in fine detail a vast array of linguistic systems that fall under the umbrella ‘English’ across the world today. Using a list of 235 morphosyntactic features, WAVE explores diatopic variation in L1, L2 and pidgin/creole varieties across the globe, illustrating the results in 96 full-colour maps, and investigates the deeper relationships between the varieties in 23 colour-coded phenetic networks. It is a veritable feast for the eyes, but there is so much detail in it that it is much more than that; it is, in fact, a huge database echoing in many ways The World Atlas of Language Structures (Haspelmath et al. 2005) in its depth and breadth.

Pre-R Dentalisation (PreRD), the dental pronunciation of /t/ and /d/ before /r/ and /ər/, is a well-known feature of English varieties throughout Ireland. PreRD is often accompanied by an /r/-Realisation Effect (RRE), whereby /r/ is pronounced as a tap after the dentalised consonant, and a Morpheme Boundary Constraint (MBC), such that PreRD is blocked by Class 2 morpheme boundaries. Although an Irish origin for PreRD has been suggested, the presence of PreRD, the RRE and the MBC in northern English dialects in a form nearly identical to what is found in Ireland suggests that the origins of PreRD lie instead in English in Britain. The possible existence of PreRD in Scotland is suspected, but definitive evidence for PreRD, the RRE and the MBC there has never been published. In this article, I provide the first detailed analysis of these features in Scotland, using unpublished data collected as part of the Linguistic Survey of Scotland. It will be seen that there is substantial evidence for PreRD, the RRE and the MBC in Scots dialects. The presence of these features in Scotland has important consequences for their history in Britain, and confirms the British origin of PreRD in Ireland.

In his foundational book on accents of English, Wells (1982: 374–5) describes the apparent merger of the vowels in the nurse and north lexical sets in Tyneside English (‘Geordie’) as follows: ‘In the broadest Geordie the lexical set nurse is merged with north, /ɔː/: work [wɔːk], first [fɔːst], shirt [ʃɔːt] (= short).’

Accents and dialects of English and Scots in Britain have been under active investigation for many decades, as reported through the Survey of English Dialects (Orton et al. 1962–71) and the Linguistic Atlas of Scotland (Mather et al. 1975–86), Wells’ three-volume compendium (1982), and a host of detailed studies of individual varieties. There are also welcome recent signs of the reintegration of variation data into theoretical discussion (see Henry 2002, Cornips & Corrigan 2005a and Trousdale & Adger 2007 for morphosyntax, as well as Anttila 2002 and Coetzee & Pater 2011 for phonology). Nonetheless, the precise structural, geolinguistic and sociolinguistic patterning of many features of vernacular Englishes in the UK is still largely unknown.

Dental pronunciation of alveolar consonants before /r/ and /ər/ is a well-known feature of traditional varieties of Irish English. This Pre-R Dentalisation (PreRD) has a number of intriguing linguistic properties, in particular an associated /r/-Realisation Effect and a Morpheme Boundary Constraint. It is less well known that PreRD is (or perhaps was) also a feature of a number of English varieties outside Ireland, particularly in traditional northern English dialects. This article analyses dialect data from northern England in order to determine the nature of PreRD there and its historical relations with the phenomenon in Irish English. In addition, it explores the phonological complexities of PreRD in light of the loss of rhoticity in traditional northern English dialects.
