This work is about resumptive and non-resumptive relative clauses (RCs) in the three big Ibero-Romance languages: Spanish, Portuguese, and Catalan. In (1), the examined structures are exemplified for Spanish: (1a.) No conozco el hombre que viste _ ayer. “I don’t know the man that you saw yesterday.” (1b.) Es este el hombre que le enviaron el libro. “This is the man to whom they sent the book.” (1c.) Es este el hombre a quien le enviaron el libro. “This is the man to whom they sent the book.” (1a.) displays a non-resumptive, or canonical, RC, which is characterized by the canonical use of a relativizing operator and a gap in the subordinate’s object position, a piece of evidence which has induced most of the generative literature to assume wh-movement of the relative operator in the sense of Chomsky (1977). The last two decades, however, have seen a big debate regarding the exact derivational analysis, starting with Kayne’s (1994) antisymmetry theory and the following focus on reconstruction and anti-reconstruction effects in RCs. This search for the correct starting site of the RC’s head noun has dismissed the original Head External Analysis (HEA) (Chomsky 1965, 1977) and led to the development of a Head Raising Analysis (RA) (Kayne 1994, Bianchi 1999, a.o.) and a Matching Analysis (MA) (Munn 1994, Sauerland 1998, a.o.). The discussion in this work argues that the data on reconstruction and anti-reconstruction effects are not sufficiently clear and reliable in order to adopt one of the head-internal analyses, i.e. a HEA or a MA. Instead, the work follows a variant of the HEA proposed for Portuguese by Rinke & Aßmann (2017), which adheres to standard assumptions about Romance syntax, and avoids the empirical problems that the other proposals have to face. Arguing that the HEA holds for all Ibero-Romance languages, this work also takes a stance in the debate around the categorical status of the relativizing element que and argues that it is always a D-element, and never of category C, i.e. there is no such thing as a relativizing complementizer (cf. also Kayne 2010, Kato & Nunes 2008, Poletto & Sanfelici 2018). The work argues that wh-movement in a HEA fashion is the correct analysis also for resumptive relative clauses as in (1b., c.), which crucially lack a gap in argument position but show a resumptive pronominal element instead. Furthermore, it takes advantage of the fact that the choice of such genetically closely related languages like Spanish, Portuguese, and Catalan enables research to address the phenomenon under consideration from a microcomparative perspective, which is “the closest we can come … to a controlled experiment in comparative syntax” (Kayne 2005: 281-282). The descriptive literature suggests that, at least for Spanish and Catalan, there are two types of a resumptive RC structure available: a simple resumption as in (1b.), including mere que, and a complex resumption structure which displays a more complex relativizer like a quien in combination with a resumptive pronoun (1c.). However, a corpus study carried out for this work reveals that speakers of the three languages behave alike insofar as the only resumptive RC used in spontaneous speech is a simple-resumption structure, while complex resumption never occurs. Additionally, a multivariate analysis shows that in all three languages, grammatical case is the most important factor when it comes to the possibility of a resumptive structure in RCs: with a dative argument, simple resumption is obligatory, while for accusative and nominative arguments, resumption is optional. The discussion concludes that simple and complex resumption constitute different phenomena also on a structural level: the latter one is argued to be a subcase of clitic doubling, and therefore, receives an analysis along the lines of Pineda (2016), who argues against a dative alternation in Romance languages and locates the (non-)realisation of the dative clitic in a transitive clitic-doubling structure outside of syntax, it being a case of silent variation along the lines of Sigurðsson (2004) and Kayne (2005). From this perspective, it follows naturally that in Portuguese, complex resumption structures are ungrammatical. Simple resumption, on the other hand, which is a possible structure in all three languages, is argued to represent the phonological counterpart of “scattered deletion”, i.e. the preferred interpretation for an A’-chain according to Chomsky (2003): in the operator position SpecCP, every feature except for the operator feature is deleted, resulting in the phonological outcome que, while in the variable position, everything but the operator is interpreted, resulting in a pronominal element according to the argument’s phi-features. This work takes a stance in the latest topics on generative analyses for relative clauses. Using not only theoretical considerations but conclusions drawn from empirical data on three languages, it offers a new perspective on pending questions and proposes to take a fresh look on supposedly outdated analyses.
