Basque sociolinguists (Unamuno & Aurrekoetxea, 2013; Zuazo, 1998) have also observed levelling patterns in the language, arguably under the influence of the standard. According to Aurrekoetxea (2006, p. 147), one of the features that seems to be undergoing change towards supra-localisation is the cross-dialectally widespread Low Vowel Assimilation (LVA); however, this phenomenon has received little sociolinguistic attention. Therefore, this study aims to gauge the depth of variation of LVA in the Western Basque town of Lezama in order to determine whether claims of levelling can be substantiated. Through an apparent-time study of two generations of Lezamans, the results reported here do not fully support a levelling interpretation of the feature. Gender-specific patterns of use emerge that corroborate observations that “women deviate less than men from linguistic norms when the deviations are overtly proscribed, but more than men when the deviations are not proscribed” (Labov, 2001, p. 367). Furthermore, consistent with recent studies (Elordieta & Romera, in press; Urtzelai Vicente, 2018), attitudes towards the ingroup are established as a determinant of the language trends in Lezama.Show less
