This study examines the variable use and the social meaning of a contact-induced phenomenon in Basque, Differential Object Marking, to explain the emergence of new variation in a minoritized language situation. The spontaneous speech of 77 Basque–Spanish bilinguals was analyzed and compared to the perception results obtained from a matched-guise experiment. I situate this analysis using emergent participant self-identification categories that lie along a continuum of Basque speaker authenticity. Production results show that DOM use increases according to a speaker's self-ascribed authenticity, but the matched-guise analyses indicate that some DOM uses may undermine the speaker's perceived authenticity. I discuss the ideological multiplicity of DOM within its semiotic landscape and consider practice-based approaches to variation in explaining this paradox. The evidence lends support for social meaning-based accounts of variation that also consider speakerhood as an agentive process, and it additionally challenges models that directly correlate language use to acts of identity.

社会意义在新巴斯克语使用者接触引起的变异中的作用

本研究考察了巴斯克语中接触诱发现象的变量使用和社会意义，差异对象标记，以解释在少数民族语言情况下新变异的出现。对 77 名巴斯克语-西班牙语双语者的自发讲话进行了分析，并将其与从匹配伪装实验中获得的感知结果进行了比较。我使用新兴的参与者自我识别类别来进行这种分析，这些类别位于巴斯克说话者真实性的连续统一体中。生产结果表明，DOM 的使用会根据说话者自认为的真实性而增加，但匹配伪装分析表明，某些 DOM 使用可能会破坏说话者的感知真实性。我讨论了 DOM 在其符号学景观中的意识形态多样性，并考虑了以实践为基础的方法来解释这个悖论。证据支持基于社会意义的变异解释，这些解释也将说话能力视为一种代理过程，并且还挑战了将语言使用与身份行为直接相关的模型。
