AbstractThis investigation examines the variable production of alveolar laterals in Barcelonan Spanish as a case study evidencing the effects of language contact between a majority language, Spanish, and a minority language, Catalan. The Catalan‐Spanish speech community constitutes a rather unique case of majority‐minority language contact, particularly within the Spanish‐speaking world, as Catalan, though a minority language in Spain, is characterized by such a high degree of linguistic vitality, linguistic capital, and social prestige in the autonomous region of Catalonia that its status as a minority language is to a degree, questionable. I account for sociophonetic variability in the production of Barcelonan Spanish /l/ by a set of linguistic (phonological context, cognate status) and social factors (gender, age, style, language dominance) that support an analysis of lateral velarization as contact‐induced and situate this case of language contact as a natural or otherwise predictable outcome of this community's sociolinguistic and sociodemographic history, notably concerning changes in immigration patterns, language ideologies, and language use in the last century. Additionally, I highlight how the gradient nature of select sociophonetic variables uniquely conditions nuanced social indexation in the speech community, specifically in the absence of any one singular or discrete, community‐wide acoustic variant.
