Identifying the sources of syntactic variation in Old Portuguese texts Esther Rinke (Goethe-Universität Frankfurt) It has early been noticed in studies on Old Portuguese (OP) that the syntax of the medieval language is more flexible than that of modern Portuguese, especially with respect to word order (Nunes 1906). Syntactic variation in OP concerns subject placement in declarative clauses (Ribeiro 1995, Fieis 2003, Rinke 2007, 2009), clitic placement in main clauses (Martins 1994), optional interpolation in subordinate clauses (Martins 2002), object placement in infinitival constructions (Rinke 2008) and article realization in argument positions. This variability has been interpreted as evidence of competing grammatical systems that indicate ongoing grammatical change (e.g. the loss of a verb second grammar or the change from a (Latin)OV to a (Romance)VO grammar). In my talk, it will be shown that the syntactic variation in OP only partly reflects ongoing syntactic change. I will focus on two phenomena: a) subject placement in declarative sentences and b) the realization/omission of determiners in argument positions. I will show that only the second phenomenon reveals grammatical change in progress whereas subject placement in declarative sentences is determined by pragmatic factors only. With respect to word order variation, I will argue that apparent verb second structures do not indicate a change from a V2 to a non-V2 grammar (Fieis 2003, Rinke 2007, 2009). The evidence of a verb second grammar in OP and of syntactic change is not conclusive because every single word order option in the medieval texts can also be generated by the grammar of modern European Portuguese. As in the modern language, subject inversion and the preposing of constituents are information structurally conditioned. Additional evidence against verb movement to the left periphery comes from clitic placement and interpolation structures in OP, as shown by Martins (2002, 2012). I will conclude that the syntactic flexibility of medieval texts can only be attributed to ongoing syntactic change when the empirical data unambiguously shows this and only if the attested variation cannot be accounted for by alternative explanations. The second case study shows that OP omits articles in contexts where the modern language requires the realization of determiners (e.g. generic noun phrases, proper names, singular count nouns in subject position (1)). (1) costume é (que) m(er)cador q(ue) alugar casa na vila & uezj~dade custom (law) is (that) merchant that rent house in-the town and vicinity q(u)is(er) fazer de soldada ... (Costumes de Santarém) want do give reward ... In modern Portuguese, examples like (1) are not grammatical because the D-head generally requires-PF realization in (ungoverned) argument positions. I will argue that the variability of article use in OP follows from a different feature specification of the DP: [+specific] D-heads require PF-realization whereas [-specific] D-heads allow for pragmatically conditioned variation. This system, which is different from both Latin and modern Portuguese, represents an intermediate step in the evolution of the Portuguese DP and therefore reflects ongoing syntactic change. If this analysis is on the right track it shows that change in progress does not necessarily involve competing grammatical systems. References: Fiéis, A.
