Grammaticalization through inherent variability

With the goal of elucidating the diachronic trajectory of a progressive, multivariate analysis is used to track the linguistic factors conditioning variation between the Spanish Progressive and the simple Present, in 13th–15th, 17th, and 19th century texts. The Progressive begins as more of a locative construction, as shown by the early favoring effect of co-occurring locatives. The direction of this co-occurring locative effect is retained over time, but the magnitude weakens relative to aspectual constraints (limited vs. extended duration contexts, dynamic vs. stative verbs), and the Progressive is increasingly disfavored in negatives and interrogatives. Increasing frequency is accompanied by changes in linguistic conditioning. An aspectual opposition arises as, in the course of speakers’ recurrent choices between variant forms, the variants develop functional differentiation.
