This paper investigates the determinants of word order variation in presentative sentences such as Er zijn geen getto’s in Brussel “There are no ghettoes in Brussels”: in specific contexts, the adjunct can precede the subject in this sentence type (Er zijn in Brussel geen getto’s). I will demonstrate that a satisfactory account of this variation requires a multifactorial approach on the intersection between Cognitive Linguistics, sociolinguistics and psycholinguistics, no matter how difficult the cross-fertilization of these disciplines is. The data reveal that word order in presentative sentences is co-determined by general motivations (Informational Prominence and Heaviness) as well as by a local constraint (Adjunct Concreteness) motivated by the constructional function of the er-initial template.
