2 Panel studies and the linguistic marketplace

Panel research, which collects repeated recordings from the same speaker as they age, is an ‘igniting’ field in sociolinguistics (Buchstaller & Beaman Reference Buchstaller and Beaman2021: 10). Panel studies allow sociolinguists to trace how and if individuals change linguistically across their lifespan (Labov Reference Labov2001; Wagner Reference Wagner2012a), broadening our understanding of the types of behaviours speakers tend to display in situations of stable variability as well as during ongoing community-wide change in progress. Such ‘intra-speaker malleability presents a severe problem for the predictive accuracy of models that rely on post-adolescent stability in linguistic habits’ (Buchstaller & Wagner Reference Buchstaller, Forthcoming and Hickeyforthcoming). This is because an apparent-time interpretation may underestimate language change if speakers align with ongoing trends, or overestimate the rate of change if speakers do not participate in ongoing shifts. Panel studies are the only type of data which can provide diagnostic information about how malleable speakers are across their lifespans (Sankoff Reference Sankoff and Brown2006; Chambers Reference Chambers2008). The panel dataset which I investigate covers the entire adult lifespan, including crucial episodes in the human experience from emerging adulthood to the entry into the linguistic marketplace over to retirement. Only such a longitudinal study which follows individual speakers across the key life stages can provide a holistic understanding of the causes of linguistic changes across the whole lifespan (Chambers Reference Chambers2008). The lion’s share of panel studies is still marred by complementary shortcomings: some only cover short periods of the lifespan (Van Hofwegen & Wolfram Reference Van Hofwegen and Wolfram2010; Wagner Reference Wagner2012b), or recordings separated by a large time gap (Buchstaller Reference Buchstaller2016; Mechler & Buchstaller Reference Mechler and Buchstaller2019). Others rely on very small speaker numbers or single speakers (MacKenzie Reference MacKenzie2017; Brook et al. Reference Brook, Jankowski, Konnelly and Tagliamonte2018). Consequently, the language sciences have not been able to establish a comprehensive picture of the linguistic malleability that characterises the adult lifespan as a whole (Wagner Reference Wagner2012b).

Whether and in which ways speakers react to ongoing linguistic changes across their lifespan depends on a cornucopia of factors, such as their social networks, social class and occupation (Buchstaller et al. Reference Buchstaller, Krause, Auer and Otte2017). For diachronically stable variables, the concept of the linguistic marketplace (Bourdieu & Boltanski Reference Bourdieu and Boltanski1975) has provided a key explanatory parameter for adult linguistic trajectories. In (professional) environments in which adherence to the hegemonically prescribed standard is beneficial, marketplace pressures are hypothesised to result in a retrenchment towards the standard form (Grama et al. Reference Grama, Mechler, Bauernfeind, Eiswirth and Buchstaller2023). Over the lifespan, the resulting pattern is u-shaped, encompassing an adolescent peak in vernacular forms followed by a middle-aged trough (Downes Reference Downes1984: 224; Buchstaller Reference Buchstaller2015: 468) and a reversal after retirement, when marketplace pressures abate (Buchstaller Reference Buchstaller2015). Such patterns have been mainly postulated based on apparent-time data and on reflections by speakers working as teachers (consider, for example, Baratta Reference Baratta2017; Cushing Reference Cushing2020). More recently, panel research has started to flesh out the workings of the marché linguistique by which speakers working in language-sensitive occupations are impacted (Bourdieu & Boltanski Reference Bourdieu and Boltanski1975: 7). Such research has revealed an occupationally niched trajectory for (ing) in the same panel dataset that is used for this study, where the most acute prescriptive pressures are placed on educators serving as linguistic role models (see Grama et al. Reference Grama, Mechler, Bauernfeind, Eiswirth and Buchstaller2023). These findings suggest that educator trajectories show retrenchment towards the standard while in classroom teaching but a notable ‘relaxation’ (Grama et al. Reference Grama, Mechler, Bauernfeind, Eiswirth and Buchstaller2023) after leaving in-session teaching.

Moreover, even though decreasing use of vernacular forms at middle age has mainly been hypothesised for stable variables (Rickford & Price Reference Rickford and Price2013; Shapp et al. Reference Shapp, LaFave and Singler2014), panel research has found similar retrenchment patterns in middle age for ongoing changes. Buchstaller (Reference Buchstaller2015) observed speakers moving away from variants indexicalised as youthful or trendy as they make their way into professional environments where adherence to the standard is expected and/or rewarded. In these cases, as for stable variables, one would expect to see reduced rates of vernacular forms amongst those middle-aged speakers who are particularly impacted by normative marketplace pressures, the ‘professionals of the language’ in the words of Bourdieu & Boltanski (Reference Bourdieu and Boltanski1975: 8).

However, there is evidence to suggest that the use of linguistic variants that are tied to the community might be beneficial for some speakers since they carry covert prestige for them. This is the case for example for professional carers such as nurses. Philip et al. (Reference Philip, Woodward-Kron, Manias and Noronha2019: 91) found that international nurses report that the use of local colloquialisms helped ‘reduce tensions in intercultural clinical communication’. Brito et al. (Reference Brito, Coutinho, de Andrade, da Costa, da Costa and dos Santos2017: 218) similarly report that using colloquial language helps professional carers to establish a better relationship between carers and patients. Note in this respect that individuals working in the tourism sector have been shown to converge towards the level of vernacularity of their interlocutors (see, for example, Coupland Reference Coupland1984 and Hall-Lew et al. Reference Hall-Lew, Couceiro, Fairs, Blake and Buchstaller2019). Their ‘local image [is thus mobilised as] part of the identity that has given [them] influence and authority by drawing on [their] authentical … roots’ (Sundgren et al. Reference Sundgren, Buchstaller and Beaman2021).

1POS is an ideal variable to test such assumptions since it contains three forms that hold very different social meanings within the context of the North-East: while [maɪ] is indexicalised as standard and [ma] is associated with female and middle-class speech, the [mi] variant has been described as stigmatised in the literature (Wales Reference Wales1996, but see below). This might lead to the hypothesis that speakers in language-sensitive occupations might be orienting towards the standard as they move into middle age (Childs Reference Childs2013). The following section briefly sketches the literature on 1POS.

3 The first-person singular possessive

1POS can be realised as [maɪ], [mi], [mə] or [ma]Footnote ¹ in the North-East of England. Linguists disagree whether [mi] should be classified as a phonetic realisation (Childs Reference Childs2013) or as ‘an extension of the object form for the possessive form’ (Anderwald Reference Anderwald, Kortmann and Schneider2004: 177). I will assume the former, since there ‘is little evidence to suggest … that those speakers who use [mi] for the possessive equate this form with objective “me”’ (Snell Reference Snell2008: 73).Footnote ²

3.1 Social constraints

Childs (Reference Childs2013) found age-graded effects in apparent-time research for her speakers from Tyneside: the younger speakers used the four variants to similar extents. In contrast, the older speakers, especially older middle-class speakers, realised higher rates of standard diphthong [maɪ]. In line with sociolinguistic theorising, she interpreted these patterns as a corollary of linguistic marketplace pressures.

In Childs’ (Reference Childs2013) research, [ma] is sharply stratified according to gender and class, being preferred by middle-class and female speakers. [mi] is generally described as stigmatised and dialectal (Wales Reference Wales1996: 14) although it can be found in almost all varieties of English in the British Isles (Kortmann & Upton Reference Kortmann and Upton2008). Note, however, that ongoing research (Moelders Reference Moeldersin preparation) on the indexicalities of [mi] on Tyneside has revealed that only 20 per cent of respondents (n=90) dislike the use of [mi] and 40 per cent report using the variant frequently themselves. In the context of the North-East ‘[i]t holds a prominent position within local consciousness, sometimes addressed directly in conversation’ (Snell Reference Snell2010: 7). This is illustrated by Dustin, a working-class man in his twenties, who comments on his use of [mi] when he is asked to read a reading passage in his second interview:

This comment implies that Dustin is both aware of his usage of the local form, and of the issue of appropriateness of this variant in more monitored contexts such as reading aloud for an unknown interviewer. It is thus not surprising that he avoids [mi] in the reading passage, in contrast to his rates in free speech (80 per cent in the first and 100 per cent in the second interview). Dustin’s comments are further corroborated by Snell (Reference Snell2008) and Grama et al. (Reference Grama, Buchstaller, Moelders, Bauernfeind, Eiswirth, Buchstaller and Beamanforthcoming), who found that [mi] is stylistically niched and preferred in informal contexts. I take these findings to mean that the form is salient and avoided in careful speech but not as stigmatised as assumed in the literature.

In Childs’ (Reference Childs2013: 55) study, ‘[mi] appears to correlate most significantly with [working] class, exhibiting a smaller gender effect’. Middle-class speakers rarely use this variant, preferring to use [ma] and Childs (Reference Childs2013: 52) appeals to class-based speech norms, arguing that ‘societal differentiation … appears to have given rise to these separate linguistic tendencies, which consequently reiterate the social distinction further’. Note also that pupils attending working-class schools favour [mi] in Snell’s (Reference Snell2008; Reference Snell2010) analysis of Teeside pupils.

4 Data

This article combines a trend and panel study to analyse the diachronic development of 1POS on Tyneside, a conurbation in the North-East of England, across the community and across intraspeaker grammar. A long history of data collection on Tyneside going back to the 1970s provides a good understanding of ongoing language variation and change in the community. All trend and panel speakers are from the North-East of England and continue to live in the geographical north, the majority still residing on Tyneside. My trend study relies on heritage data to construct a socially balanced sample of 21 speakers who were recorded in 1994 as part of the Phonological Variation and Change in Contemporary Spoken English (PVC) corpus and a socially matching sample of 21 different speakers who were interviewed in 2013–17 as part of the Diachronic Electronic Corpus of Tyneside English (DECTE; see Allen et al. Reference Allen, Beal, Corrigan, Maguire, Moisl, Beal, Corrigan and Moisl2007; Corrigan et al. Reference Corrigan, Buchstaller, Mearns and Moisl2012; Beal et al. Reference Beal, Corrigan, Mearns, Moisl, Durand, Gut and Kristofferson2014). This community trend corpus (table 1), which includes 1,642 possessive tokens, allows me to report on the development of 1POS in the North-East since the 1990s.

Table 1.

Social matrix of trend sample

To explore the development of 1POS amongst the younger age ranges, I also created a second, four-wave trend set (n=987) consisting only of speakers in their twenties. While issues of data availability meant that the young trend sample was not perfectly socially balanced, as table 2 reveals, five to eight young speakers were pulled from corpora collected in the Tyneside region from the 1970s, the 1990s, the early 2000s and the 2020s. These data were drawn from DECTE (Corrigan et al. Reference Corrigan, Buchstaller, Mearns and Moisl2012) as well as the Language Variation and Change Project (see Grama et al. Reference Grama, Mechler, Bauernfeind, Eiswirth and Buchstaller2023 for a detailed introduction of the project and the panel corpus).

Table 2.

Social matrix of young trend sample

These two separate trend datasets are complemented by the Language Variation and Change (LaVaLi) panel corpus (see table 3). This novel and dynamic panel corpus consists of 25 speakers who were recorded twice: the first recording of the young and middle-aged brackets was also part of the DECTE project, which has been collecting language data on Tyneside since 2006 (see Allen et al. Reference Allen, Beal, Corrigan, Maguire, Moisl, Beal, Corrigan and Moisl2007; Corrigan et al. Reference Corrigan, Buchstaller, Mearns and Moisl2012; Beal et al. Reference Beal, Corrigan, Mearns, Moisl, Durand, Gut and Kristofferson2014). In order to create the panel corpus, the LaVaLi team contacted as many speakers as possible to rerecord them ten years after the first recording took place. Despite the typical problems that come with the creation of panel corpora, we managed to rerecord 25 speakers. The resulting panel sample is stratified by age (4–6 speakers per age group) and gender.

Table 3.

Social matrix of panel sample

All recordings consist of ethnographic interviews lasting approximately sixty minutes. For maximum comparability between the timepoints, the interview setting was kept constant, and interviewees were given prompts in the second interview to ensure that similar topics were covered at both timepoints. Apart from the oldest speakers, who were interviewed individually by a fieldworker from the University of Newcastle, all other panel speakers were recorded in dyads with a friend, family member or acquaintance. These pairs remained the same for the second interview.

The six consecutive age bands cover the entire adult lifespan from emerging adulthood (Arnett Reference Arnett2000) to speakers’ entry into the linguistic marketplace, the pressures of middle age (including life-stage markers such as parenthood or increased professional responsibilities such as mentoring young colleagues or trajectories towards senior positions) until retirement.

5 Analytic methods

The data were orthographically transcribed, annotated and time-aligned in ELAN (Lausberg & Sloetjes Reference Lausberg and Sloetjes2009). All possessive tokens were identified in LaBB-CAT via regular expressions (Fromont & Hay Reference Fromont and Hay2012). I coded each token auditorily in Praat and classified them as [maɪ], [ma], [mi] and [mə] (with the latter being excluded from the analysis). To ensure consistency, all tokens were blind coded twice with an average time difference of six weeks. The data (the youngest and the oldest cohorts) was also coded for a third time by external coder and the intercoder reliability between my coding and their coding was 93.69 per cent. For inconsistent tokens, the trajectories of F1 and F2 were visually inspected in Praat; ambiguous and indeterminate tokens were excluded, as were possessives that occurred in interruptions or during stretches of poor audio quality (see Blake Reference Blake1997).

Excluded linguistic environments for both the panel and trend study are possessives followed by some variation of God (e.g. Oh my God/Gosh/Goodness) since these are categorically [maɪ] and stressed (see Childs Reference Childs2013). Reflexive pronouns (myself) are also not considered because they cannot be coded for the alienability of the following noun and have an invariable following phonetic environment.

To analyse the linguistic constraints in the panel study, I drew on previous research as described above. Following Hollmann & Siewierska (Reference Hollmann and Siewierska2007), only possessives directly followed by a noun were included. I coded for the presence or absence of word-level stress as well as the following phonetic environment, dividing the following nouns into those beginning with a vowel and those beginning with a consonant (Snell Reference Snell2008; Childs Reference Childs2013). My coding strategy for alienability follows previous research by subdividing the noun following the 1POS into kinship terms and body parts, which have been described as spearheading the (in)alienability hierarchy in equal parts as they are positioned at the top of the alienability hierarchy (Hollmann & Siewierska Reference Hollmann and Siewierska2007; Childs Reference Childs2013). All remaining nouns were categorised as other. For a complementary operationalisation of alienability, I calculated the relative frequency of the following nouns in my data in line with Childs (Reference Childs2013) and Hollman & Siewierska (2007) and found that the average relative frequency of possessed kinship terms is 17 per cent, of body part terms 14 per cent and of other nouns 6 per cent, confirming previous findings by Childs (Reference Childs2013) and Hollmann & Siewierska (Reference Hollmann and Siewierska2007), who found similar frequencies for possessed nouns their data.Footnote ⁴

For informant gender, I relied on the information provided by the interviewees themselves, which resulted in a binary coding scheme (male versus female). Since Grama et al. (Reference Grama, Mechler, Bauernfeind, Eiswirth and Buchstaller2023) found that the educator status of the speakers played a significant role in the variable choice in the same panel dataset, I classified the speakers according to their educator status as current, none and former.Footnote ⁵ Social class was derived from the Standard Occupational Classification 2010 and divided into a ternary category: those speakers who are upwardly mobile (i.e. those who move from working-class to middle-class from T1 to T2) as opposed to those who remain stable working-class and middle-class. Students were classified based on their parents’ socioeconomic status.

RStudio (RStudio Team 2015) was used to conduct the statistical analyses, including mixed effects regression models (fit via the lme4 package, Bates et al. Reference Bates, Mächler, Bolker and Walker2015). I followed previous research (Hollmann & Siewierska Reference Hollmann and Siewierska2007) in collapsing [ma] and [mi] into one category, which left me with a binary opposition: reduced forms versus standard [maɪ]. Because of the vastly different indexicalities of the two reduced variants, I also ran a separate regression model comparing the reduced variants separately. All models included all linguistic and social constraints as fixed effects and speaker as a random effect. To explore if the constraints remain stable across the lifespans of my panel speakers, I furthermore investigated interactions between the time of recording and the respective constraint. These analyses were done separately for each age bracket to explore (in)stability for each cohort in the panel dataset. Variance Inflation Factor (VIF) analysis via the car package (Fox & Weisberg Reference Fox and Weisberg2019) indicated that there is little or no multicollinearity among the predictor variables. Table 4 summarises the coding scheme employed in the following analyses.

Table 4.

Summary of linguistic and social constraints

Overall, the two-wave community trend sample consists of 1,642 tokens, of which 831 (51%) are realised as [mi], 508 (31%) as [maɪ] and 303 (18%) as [ma]. The trend study with only young speakers comprises 987 tokens, of which 350 (35%) are realised as [mi], 350 (35%) as [maɪ] and 287 (30%) as [ma]. The panel study, finally, contains 1,571 tokens of 1POS altogether, of which 718 (46%) tokens are realised as [mi], 445 (28%) as [maɪ] and 408 (26%) as [ma].

6 Trend study

Childs’ (Reference Childs2013) apparent-time study shows that older speakers use [maɪ] more often than younger speakers. Note in this context that the time slices used in her study are relatively broad, with younger speakers aged 18–26 and the older cohort 40–77. The two trend studies used in the present study add diachronic nuance to the development of 1POS in real time. Analysis of the community trend data (n=1,642) allows me to compare two snapshots of the Tyneside community collected on average fifteen years apart.

Figure 1 illustrates the diachronic competition between the two reduced forms: while [maɪ] stays relatively stable, [ma] increases slightly across time, an expansion that is primarily at the expense of [mi]. This change, which is highly significant (χ² (2) 23.179, p < 0.001), does not align with Childs’ (Reference Childs2013) apparent-time study, which showed that older speakers preferred [maɪ] and produced [ma] and [mi] in equal amounts. The younger age cohorts, on the other hand, used [ma], [mi], [maɪ] and [mə] to the same extent. What might lie behind these disparate findings?

Figure 1.

Overall development of 1POS in trend sample

Figure 2 adds an apparent-time angle to these diachronic trends by comparing the age groups at each time point: here, the ongoing change towards [ma] depicted in figure 1 is visible across apparent time, with younger speakers producing increasingly higher ratios of [ma]. Amongst the younger age brackets, there is also a clear incrementation across real-time (trend) data (∆18% between T1 and T2): the young speakers in the 2000s produce the highest frequencies of [ma] of all speakers by far. This is the only intra-cohort comparison which is significant for this part of the trend study (χ² (2) 36.556, p- value < 0.001). Since standard [maɪ] is relatively stable for the youngest cohort – only increasing ever so slightly across time – these rising [ma] rates come at the direct expense of [mi], which declines by 21 per cent.

Figure 2.

Development of 1POS by trend cohort

While the middle-aged speakers retain middling rates of [ma] in both subcorpora (∆1%), note that this age group shows the largest increase in use of [maɪ] across time (∆10%). Amongst the oldest speakers, rates of [maɪ] and [ma] remain relatively stable, the latter at low frequencies. Note also these oldest speakers are the age group with increasing rates of [mi]. However, neither of these trends were significant. What can be inferred from these plots is that the variant [ma] has progressively increased its share within the variable since the 1990s. Hence, while rates of [ma] creep up in apparent time, between the generations, it is only the youngest speakers that show a propagation of [ma] in real time.

The young trend study (in figure 3), which comprises speakers in their twenties and early thirties recorded between the 1970s and the 2020s, adds further detail to this process of incrementation of [ma] in the system of 1POS.

Figure 3.

Development of 1POS for young trend speakers

Figure 3 lends support to the hypothesis that [ma] might indeed be a newcomer that is increasing at the expense of [mi].Footnote ⁶ The variant was not used by speakers in their twenties in the 1970s at all, only appearing in the 1990s (with a share of 22 per cent of the system). By 2007–13 [ma] rates have surged to 40 per cent, which stabilise by 2021 (40 per cent). The inverse is true for [mi], which was the preferred variant in the seventies (72 per cent) but has since become the least favoured form amongst the most recent twenties cohort (with only 14 per cent the 2020s data). Based on these trend data, I hypothesise that [ma] entered the system sometime in the 1980s, increasing over the following decades amongst younger speakers. Indeed, this trend suggests that [ma] might be making its way into the linguistic system of speakers in the North-East. Standard [maɪ] grows gradually across time for the young (see figures 1 and 2) and middle-aged speakers (see figure 2). One might hypothesise that the latest jump in [maɪ] usage amongst the youngest trend cohort might be an artefact of the dearth of male speakers in this particular group (consider table 2). However, an analysis of the distribution of 1POS by gender (see figure 4) suggests that this is not the case. To test the effect of gender on variant choices in 1POS, let us consider figure 4, which includes only the community trend sample and plots the diachronic development of the possessive determiner stratified by gender.

Figure 4.

Development of 1POS stratified by gender

The comparisons between the 1990s and the 2000s suggests that incoming [ma] started out as a female-led change, by ‘women with a particular ability to confront established norms and the motivation to defy them’ (Labov Reference Labov2001: 516; consider also the ample sociolinguistic literature on women at the forefront of supralocal changes, e.g. Docherty & Foulkes Reference Docherty, Foulkes, Foulkes and Docherty1999). While the gender differences in the 1990s are highly significant (χ² (2) 13.128, p-value=0.001), by the 2000s men seem to have caught up with this development as the difference between male and female speakers fails to reach significance (χ² (2) 5.643, p-value=0.06). A consequence of the male speakers’ increasing [ma] rates could be that standard [maɪ] is favoured by men in the 1990s data, which melts away by the 2000s.

7 Panel study

A series of mixed effects models were fit to the data with the phonetic realisation of 1POS as the response variable; [maɪ] was set as the baseline level. Speaker was included as a random effect, and I tested for the gamut of linguistic and social predictors illustrated in table 4.Footnote ⁷ Because of the varying indexicalities of the three variants, I fit one model exploring standard [maɪ] versus reduced [mi] and [ma] combined (table 5) as well as a model only comparing the two reduced forms (table 6).

Table 5.

Results of mixed effects regression model comparing [maɪ] vs reduced forms ([mi] and [ma])

Not significant: following phonetic environment, gender, social class, age, recording*stress, recording*age, recording*alienability.

Odds ratios > 1 favour the standard [mai], odds ratios < 1 favour reduced variants [mi] and [ma].

Table 6.

Outcome of a mixed effects regression model comparing reduced [ma] vs [mi]

Not significant: following phonetic environment, gender, social class, stress, recording*stress, recording*age, recording*alienability.

Odds ratios > 1 favour reduced [ma], odds ratios < 1 favour reduced [mi].

Let us consider the linguistic constraints on the standard versus reduced model first. In line with Childs (Reference Childs2013) – and contrary to Snell’s (Reference Snell2010) finding that following vowels favour [maɪ] – the following phonetic environment did not come out as significant in the model depicted in table 5. Stress, however, was highly significant, with stressed contexts favouring the occurrence of [maɪ]. Out of the 1,438 unstressed tokens overall, 325 were [mai] (73 per cent of all unstressed tokens). There were 133 stressed tokens, of which 120 were [mai] (90 per cent of all stressed tokens). Every speaker in the sample used the standard more frequently in stressed contexts, which confirms Childs’ (Reference Childs2013) assertion that stress is a significant predictor for standard [maɪ].

The alienability of the following noun also plays an important role in the choice between full versus reduced 1POS variants. While other nouns tend to favour standard [maɪ], reduced variants are favoured with body part and kinship terms. This corroborates findings by Childs (Reference Childs2013) and Hollmann & Siewierska (Reference Hollmann and Siewierska2007). The fact that kinship and body part terms occur with the reduced variants most often in my data also confirms Haspelmath’s (Reference Haspelmath2008) assertion that nouns with a higher relative frequency are more likely to trigger a reduced possessive marking. While the extralinguistic constraints on 1POS will be explored below, let us now consider the linguistic factors that determine the choice between the two reduced variants.

The following phonetic environment was also not significant in the model comparing the two reduced variants. In contrast to the first model, however, stress did not come out as a significant predictor in a model that explores the factor’s conditioning choice between the two reduced forms. I interpret this finding to mean that while the full form is generally preferred in stressed contexts, the choice between unstressed realisations is not sensitive to stress. Alienability was again significant, with body part and kinship terms favouring [mi] if compared to other nouns, so it seems as if alienability not only impacts the choice between full and reduced form but also between the reduced variants themselves.

As a last step for the linguistic constraints, I ran separate regression models for each age cohort, testing for interactions between time of recording (T1 versus T2) and stress and alienability. Interaction terms were included in models that predict [maɪ] versus reduced forms, as well as in models that predict [ma] versus [mi]. This allows me to investigate if and indeed how these constraints change across the speaker’s lifespan. I merely report on the significant interactions here. With the sole exception of the early twenties and the sixties cohorts, all other age groups maintain a stable constraint system as they age. The significant interaction term (p-value=0.009) for the early twenties cohort amounts to a shift in preference from disfavouring [ma] with kinship terms in T1 to favouring [ma] in these contexts in T2. This is illustrated in figure 5.

Figure 5.

Alienability (contrast between reduced variants) for the early twenties cohort

Intraspeaker changes in the grammar conditioning variable choice have been reported for post-adolescent speakers before (Buchstaller et al. Reference Buchstaller, Krause-Lerche and Mechler2021; Beaman Reference Beaman2022). The finding that the youngest group, speakers in their twenties, display malleability in their constraint system might thus not seem overly surprising. The other interaction term, however, is observed for speakers in the sixties. For this cohort, the interaction of stress and recording was significant for the model comparing standard [maɪ] with the reduced variants (p-value=.005). As is illustrated in figure 6, while the standard is more likely to occur in stressed environments in both recordings, the effect becomes significantly more pronounced in the second recording for this cohort.

Figure 6.

Stress (standard versus reduced) for sixties cohort

Hence, the significant effect for the oldest speakers seems more indicative of a consolidation of the constraint system, where the effect of a predictor is becoming more focused, rather than a true reorganisation. Hence, while there is some evidence that the changes in the constraint system can occur in speakers until well into their sixties (Buchstaller et al. Reference Buchstaller, Krause-Lerche and Mechler2021; Beaman Reference Beaman2022), more research is needed to explore the extent to which older speakers show change in the grammatical conditioning that underpins variable choices across time (see Pichler et al. Reference Pichler, Wagner and Hesson2018).

Let us finally explore the social situatedness of the change in 1POS. Gender does not come out as a significant factor in either model, despite the change in 1POS originating as being female-led. The time of recording, however, is significant in both models – with a significant decrease of both [ma] and [maɪ] and a concomitant increase of [mi]. I take these findings to mean that the realisation of 1POS is changing both in the community and across the lifespan of the panel speakers. Age cohort as a factor is only significant for the model comparing reduced forms [mi] and [ma], with every single age group being different from the early twenties, the reference level in the model. Post hoc tests via the emmeans package in R (Lenth Reference Lenth2022) reveal that the older cohorts do not differ significantly from each other. This can be attributed to the youngest speakers’ elevated rates of incoming [ma], as shown in figure 7.

Figure 7.

Distribution of 1POS across cohorts in the panel sample

In the time period covered by the panel corpus, the youngest cohort produce decreasing rates of [ma] and orient towards standard [maɪ] as they get older. This movement away from the incoming form did not come out significant in a separate mixed effects model run on this cohort (the p-value of recording was 0.877), but this numerical trend away from [ma] might be a correlate of these speakers’ entry into the linguistic marketplace. Note in this respect that the late twenties cohort produce no [ma] at all (but they show high and stable rates of [mi]). Similarly, the thirties, forties and fifties cohorts slightly increase their [mi] rates across the recordings while [ma] stays stable at relatively low rates. Crucially, except for the oldest cohort, none of the age groups in my panel sample appears to be going along with the community-based trend towards decreasing [mi] and concomitant increase of [ma]. Quite the opposite, [mi] is relatively stable across the panel sample with only a slight increase across the lifespan (44% versus 49%, χ² (1) 3.3708, p-value = 0.06636).

Not much is known about retrograde changes (but see Sankoff & Wagner Reference Sankoff and Wagner2006; Reference Sankoff and Wagner2020), which have hitherto been mainly attributed to highly educated speakers moving away from community-led changes towards incoming forms. In my data, there seems to be the opposite effect: speakers moving towards (or retaining) variants that have been described as stigmatised in the community at large. The sociolinguistic enterprise has drawn our attention to the fact that, especially amongst communities characterised by a strong sense of local belonging, some professional trajectories are aided and abetted by performances that tap into local linguistic forms as social capital. While these findings have been mainly reported in the tourism sector (Schilling-Estes Reference Schilling-Estes1998; Hall-Lew et al. Reference Hall-Lew, Couceiro, Fairs, Blake and Buchstaller2019), research has found that nurses use colloquial speech strategically to establish ‘a positive interpersonal relationship with their patient’ (Brito et al. Reference Brito, Coutinho, de Andrade, da Costa, da Costa and dos Santos2017: 218; see also Philip et al. Reference Philip, Woodward-Kron, Manias and Noronha2019). My panel data support this finding: the three panel speakers who work as nurses in the healthcare sector tend to employ vernacular forms for the performance of friendly or compassionate stances: Erica, Samantha (nurses) and Lucille (a charity worker in the healthcare sector) maintain relatively high and stable [mi] rates across their lifespans. Erica, a mental health nurse in Northumberland, reflects on the fact that her accent allows her to do local identity work, fostering a joint sense of belonging and thus supporting her professional goals:

I would venture that linguistic strategies indexicalised as local are particularly apt at fostering such a sense of belonging since they are tied to a shared deep geography of belonging (Hall-Lew et al. Reference Hall-Lew, Couceiro, Fairs, Blake and Buchstaller2019). Note also that Sundgren et al. (Reference Sundgren, Buchstaller and Beaman2021) have shown that deeply held perceptions of local rootedness of certain linguistic forms can show up in gendered linguistic trajectories. They find that some geographically non-mobile male speakers in Eskilstuna (Sweden) use high rates of localised linguistic forms with covert prestige to signal their belonging to the autochthonous community while signalling local expertise. This trajectory is illustrated in my panel data by two speakers: Jake is a social riser who works as a clerk in the local Tyneside government. He shows retrograde movement towards [mi] (from 16 to 79 per cent) against the community trend as he rises through the ranks of the lower to mid echelons of his local council. Andrew, similarly, draws on the covert prestige of localised vernacular [mi]. Starting out as a shop assistant in T1, Andrew has opened a local barbershop by T2. In extract (3), Andrew reflects on his accommodative behaviour to his customers as well as on the value of the vernacular as a male bonding strategy, reporting that his language has become more ‘blokey’ since he has opened his own neighbourhood shop. Note that Andrew’s rates of [mi] increase from 19 per cent in T1 to 50 per cent by T2. As illustrated in the extract, Andrew also draws on localised first-person plural possessive wor, northern past tense form sat, T-to-R, as well as glottal(ised) realisations of /t/ for his ‘blokey’ performance within an indexical landscape that is historically tied to locally rooted, blue-collar values (Trudgill Reference Trudgill1972; Lawson Reference Lawson2020).

Finally, let us consider the use of 1POS amongst educators, those ‘professionals of the language’, whose ‘lives and work would require them to [demonstrate] access to the language variety legitimized by the dominant ideology’ (Sankoff et al. Reference Sankoff, Cedergren, Kemp, Thibault, Vincent, Fasold and Schiffrin1985: 108). Critical school research (Cushing Reference Cushing2020; Cushing & Snell Reference Cushing and Snell2023) has argued that teachers are generally expected to serve as linguistic role models for their students within the context of the British educational system, expected to promote the ‘high standards of literacy, articulacy and the correct use of standard English’ (Department for Education 2021: 11). Baratta (Reference Baratta2017, Reference Baratta2021) has reported that teachers feel pressured to adhere to prescriptive superimposed norms and orient towards accents which are indexicalised as professional. But to date, such research has been predominantly based on surveys with teachers and policy documents. It is thus unclear how and to what extent educators’ linguistic trajectories are impacted by such prescriptive pressures ‘where language is aggressively surveilled and policed’ (Cushing & Snell Reference Cushing and Snell2023).

The teachers in my panel data show different reactions to the prescriptive pressures of the ‘marché scolaire’ (Bourdieu & Boltanski Reference Bourdieu and Boltanski1975: 7). Table 7 shows the teachers in the sample and their proportional use of these variants of 1POS before, during and after active teaching duty.

Table 7.

Overview of teachers in panel sample

Of the three youngest panel speakers who move into in-session teaching between T1 and T2, Amelia and Lynn do not seem to be impacted by prescriptive pressures (yet), which has also been found for their realisation of (ing) (Grama et al. Reference Grama, Mechler, Bauernfeind, Eiswirth and Buchstaller2023). The fact that Lynn increases her [mi] and [ma] rates is not surprising given that she reports that she teaches in the same school she attended when she was a student. In a similar vein, related research has interpreted Amelia’s slight increase in vernacular forms as her ‘newfound confidence [being] reflected in her linguistic behavior’ (Grama et al. Reference Grama, Mechler, Bauernfeind, Eiswirth and Buchstaller2023: 20). Sally’s orientation towards [mi] might be due to her high dialect loyalty as she explicitly mentions not changing her accent any more in T2 (20:40–20:51): ‘when I first started teaching I was very conscious of it […] and I would perhaps modify the way that […] I spoke […] but I try not to now I try to actually just be me.’

The third student, Charlotte, is an illustrative case of retrenchment because of marketplace pressures as she is moving into the marché scolaire: at T1, Charlotte is a university student, and at T2 she has become a PhD student, engaging in regular tutoring and lecturing at university level. Not surprisingly, thus, her rates of the stigmatised form [mi] plummet from 67 to 5 per cent, while she increases her rates of [ma] (15 per cent) and standard [maɪ] (79 per cent). In her T2 interview, Charlotte reports that she is aware of the pressures that come with her profession, not only because of her own experience in the classroom but also because she is familiar with indexicalities associated with certain linguistic variants in the North-East. Charlotte’s withdrawal from socially costly forms can thus be interpreted as a reaction to prescriptive expectations, leading her to opt for ‘safer’ forms.

The older and middle-aged panel subcorpora also offer an opportunity to explore the linguistic repercussions of leaving the marché linguistique. Grama et al.’s (Reference Grama, Mechler, Bauernfeind, Eiswirth and Buchstaller2023: 2) panel research on (ing) suggests that moving out of the monitored environment that characterises in-session teaching tends to go hand in hand with ‘post-educator relaxation’ towards non-standard forms. While their analysis focused on stable variability in the nasal alternation, my data allow me to test these claims based on a community-wide change in progress. The panel corpus contains four educators who have stepped away from in- session teaching, either due to retirement (Fred, Richard, Margret) or because of career changes (Nathan left teaching to pursue a PhD in music). Crucially, as table 7 reveals, three of these speakers increase their [mi] rates as they exit (and put distance) between themselves and the marché scolaire. This retrograde change is illustrated in excerpt (4), produced by Fred, who reports that he closely monitored his way of speaking when working as a professional communicator in a local grammar school.

Fred’s impressionistic remarks are mirrored in his linguistic trajectory: His [mi] rates increase from 8 to 16 per cent between T1 and T2. In a similar vein, schoolteacher Margret only uses [maɪ] and [ma] while she is in active teaching duty but resorts back to localised [mi] (50 per cent) after retirement, at the expense of standard [maɪ] (see table 7). I interpret the increase of [mi] after retirement as an instantiation of the ‘tail’ in old age, whereby speakers become increasingly vernacular as they move out of the linguistic marketplace (Labov 200; Buchstaller Reference Buchstaller2006).

These data support Grama et al.’s (Reference Grama, Mechler, Bauernfeind, Eiswirth and Buchstaller2023) finding of post-educator relaxation amongst speakers who move out of the marché scolaire, either due to retirement or due to a change in profession. My data thus corroborate their claim that the increase in proscribed form [mi] is not strictly tied to speakers’ chronological age but is a function of the respective prescriptive pressures individuals are exposed to at individual life stages (see Pichler et al. Reference Pichler, Wagner and Hesson2018). Finally, the retrenchment away from socially costly forms and towards the proscribed standard is not uniquely tied to stable age-graded variables. My analysis reveals that the same pattern holds for variables undergoing change, provided that they are associated with meanings considered inappropriate in professions in which adherence to the prescribed standard is valued.
