LANGUAGE CHANGE AND SOCIOLINGUISTIC FACTORS

Language change is ubiquitous and intimately tied to social context. This paper synthesises recent and foundational literature to analyse how sociolinguistic factors drive linguistic innovation and diffusion. We review empirical studies on social networks, age and gender effects, language contact, and demographic context, and compare major theoretical frameworks (variationist sociolinguistics, network theory, functional adaptation, contact models). We find that innovations often emerge in peripheral or loosely connected communities (e.g. adolescents, women, mobile workers) and spread via weak social ties, whereas densely knit conservative groups tend to slow or resist change. Languages with high proportions of adult L2 learners tend to simplify morphosyntax, whereas socially stable or isolated communities maintain complexity. An integrated model is presented (diagram) to illustrate the pathways from social variables to change outcomes. This analysis confirms that language change is not random but patterned by social structures (Smith 2022; Laitinen et al. 2020; Kerswill 1996). It also notes gaps and limitations (e.g. under‐studied syntactic change, reliance on phonological data, largely Anglophone bias). The paper concludes that rigorous modelling of language change must combine social, cognitive, and contact perspectives, using both quantitative and qualitative methods.
