“…4 Blommaert and Backus (2013, p. 6) summarize the discussion as "(a) an increasing problematization of the notion of 'language' in its traditional sense -shared, bounded, characterized by deep stable structures; (b) an increasing focus on 'language' as an emergent dynamic pattern of practices in which semiotic resources are being used in a particular wayoften captured by terms such as 'languaging', 'polylingualism' and so forth". Although the focus of most third wave sociolinguistic studies has been Western settings, such conclusions have also been reached in work carried out in Casamance (e.g., Dreyfus & Juillard, 2005;Goodchild, 2016Goodchild, , 2019Goodchild & Weidl, 2019;Juillard, 1990Juillard, , 2005Weidl, 2019). However, finegrained variationist studies focusing on individual features are confounded by the fact that this setting involves so many unstandardized and often undescribed languages -how can we identify variation if we have no baseline to compare it to?…”
