European Portuguese, like other Romance languages, display a great amount of word order variation. Out of the six logically possible permutations between Subject, Verb and Complement in a transitive sentence, five are possible: SVO, VSO, VOS, OVS and OSV. The primary goal of this book is to provide an analysis of the several positions where the subject may surface in European Portuguese. Departing from an architecture of the clause as sketched in early minimalist work, containing two subject-related functional categories above VP (AgrP and TP), it is shown that the subject may surface in all potential landing sites: Spec,AgrP, Spec,TP and Spec,VP. Moreover, just like any other argument of the clause, it is claimed that subjects also have the possibility of surfacing in a left-dislocated position, arguably adjoining to the clause's left periphery. It is shown that there is no free variation. Each of these positions may be occupied by the subject, only if two requirements are met: i) The position is made available by syntax; ii) The position does not violate any interface condition. In other words, the following model is argued for: syntax generates legitimate outputs. At the interface levels, each output may be selected or filtred out, according to requirements of the interface. The picture emerging from the proposal made in this book is the following: syntax proper does not need to refer to conditions best placed at the interface. All that is needed from syntax is that it generates an array of well-formed outputs. Such outputs may be evaluated a posteriori by each of the interfaces. If they meet requirements of the interface, they are selected as legitimate. If, on the contrary, some interface condition is violated, they are ruled out. Under this approach, three in-dependent results are derived: i) an explanation is found for the patterns of word order variation; ii) syntax proper may be reduced to its own tools, not having to manipulate semantic, discourse or prosodic variables; iii) the intuition that European Portuguese is an SVO language is derived: this word order corresponds to the one in which the subject occupies the only specifier position in which the other interfaces play no role.

The architecture of the human language faculty has been one of the main foci of the linguistic research of the last half century. This branch of linguistics, broadly known as Generative Grammar, is concerned with the formulation of explanatory formal accounts of linguistic phenomena with the ulterior goal of gaining insight into the properties of the 'language organ'. The series comprises high quality monographs and collected volumes that address such issues. The topics in this series range from phonology to semantics, from syntax to information structure, from mathematical linguistics to studies of the lexicon.

By combining theoretical analysis and empirical investigation, this monograph investigates the status of interfaces in Minimalist linguistic theory, second language acquisition and native language attrition. Two major questions are currently under debate: (1) what exactly makes a linguistic phenomenon an ‘interface phenomenon’, and (2) what is the specific role that the interfaces play in explaining language loss and persistent problems in second language acquisition? Answers to these questions are provided by a theoretical examination of the role that economy and computational efficiency play in recent Minimalist models of the language faculty, as well as by evidence obtained in two empirical studies examining the acquisition and attrition of two interface phenomena: Spanish subject realization and word order variation. The result is a new definition of ‘interface phenomena’ which deemphasizes syntactic complexity and focuses on the effect of interface interpretive conditions on syntactic structure. This work also shows that representational deficits cannot be ruled out in the acquisition and attrition of interface structures.

This book presents theoretical and experimental analyses of the nature of early verbs. At around the age of two years old, children start to combine words and produce their first verbs. Verbal items appear later than nouns in a child’s speech and refer to the relational concepts in the world that are represented in syntax through the argument structure. The central set of data investigated here is based on the analysis of the features of first verbal productions in Italian. Since the appearance of verbs implies the mastery of a mapping procedure between syntactic positions and semantic roles, the syntactic regularities found for each lexical verb class suggest that the relation at the syntax-semantics interface is well-established early on. The non-adult-like sentences are those which involve the mastery of the scope-discourse semantic interface or higher functional syntactic categories. The analysis of the delay in the production and comprehension of some constructions here uncovers some general characteristics of language acquisition devices.

In the last decade, the notions of topic and focus have come to play an increasingly relevant role in theoretical linguistics. Although these notions are often taken for granted, they are still poorly understood. This study offers a detailed analysis of the precise definitions of these and related terms (theme, topic, background, given information, focus, contrast, etc.) as well as of their combination into information structures such as the topic-focus and background-focus articulations. It recommends pursuing a feature-based typology of topics and argues against a dual nature of focus (i.e. presentational vs. contrastive). Central questions addressed are the analysis of subjects in Spanish and English (DP vs NP and null vs. preverbal vs. postverbal) and the nature of constructions such as topicalization, left-dislocation, and focus preposing. Further, it is proposed that in Spanish information structure can be read off the syntax: while an overt DP in the preverbal specifier subject position is interpreted as the topic in a topic-focus articulation, one or more left-or right-dislocated phrases are interpreted as part of the background in background-focus/focus-background structures.

It is quite remarkable that, after over a half-century of generative grammar, there is still uncertainty with respect to the analysis of preverbal subjects in a number of languages. According to canonical analyses, preverbal subjects are arguments (A-elements). However, following non-canonical analyses, preverbal subjects are not arguments, but rather A’-elements that behave like topical preverbal direct and indirect objects, which have received a CLLD analysis in the literature (e.g. Cinque 1990). The implications of this debate are far-reaching for generative theory: if preverbal subjects are non-arguments, one must question the universality of the EPP (as in e.g. Alexiadou & Agnostopoulou 1998), as well as its associated features and feature-strengths. Galician is an underdocumented Romance language within the generative paradigm. In this book, I develop an experimental program for establishing clausal word order preferences for a number of information structure contexts. The preference data suggest that preverbal subjects behave like canonical elements, and not CLLD elements. These results inform the model of the preverbal field that I propose for Galician, which also takes into account the enclisis-proclisis divide and reco.

In Theoretical and Experimental Aspects of Syntax-Discourse Interface in Heritage Grammars, Tanya Ivanova-Sullivan investigates comprehension and production of anaphoric dependencies with null and overt subject pronouns. She discusses the divergent behaviour of the heritage speakers of Russian by providing a closer look at their proficiency level, quantity of input and order of language acquisition. She explains the results with various degrees of successful application of pragmatic principles and efficiency in allocating cognitive resources. The contribution of the monograph lies in the discussion of theoretical and experimental issues related to anaphora resolution along with an investigation of all aspects of representation and processing of anaphoric pronouns by various kinds of bilinguals: heritage speakers, L2 learners and L1 attriters.
