DIFFERENTIAL OBJECT MARKING AND CLITIC DOUBLING IN SPANISH AND CATALAN: THE GRAMMATICALIZATION OF TOPICALIZATION DEVICES

I argue for a two-fold connection between DOM and CLD in Spanish and Catalan varieties which can be traced back to both phenomena being the result of the grammaticalization of topicalization structures. Under this view, the synchronic inter- and intralinguistic variation found in these varieties can be interpreted in a way that the varieties have not reached the same level of grammaticalization.
