This volume is a collection of previously unpublished articles focusing on the following aspects of Portuguese syntax: clause structure, clitic placement, word order variation, pronominal system, verb movement, quantification, and distribution of particles. The articles are written within the principles and parameters framework and contrast Portuguese with other Romance languages.

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.

Over the last three decades, Brazilian Portuguese bare nominals have turned into a hot topic in the cross-linguistic study of nominal syntax and semantics. This contribution is the first comprehensive, book-length treatment of the issue, covering both the long-standing discussion about the adequate analysis of these forms as well as the establishment of a solid empirical basis for future research. The book goes further than previous accounts in also taking into consideration the phonetic-phonological dimension, showing the advantages of a more comprehensive account. The empirical section outlines an innovative approach in which different methods and data types are combined and focuses on the underresearched definite / specific / referential uses and interpretations of bare singulars. The book also addresses the traditional topics in the study of bare nominals – genericity, the mass/count distinction, NP-internal plural agreement, the NP/DP distinction, and syntax-semantics-phonology interface questions – in the light of the new findings.

This volume addresses core issues on complement clauses, focusing on Portuguese (European, Brazilian and Mozambican varieties). It contributes to the discussion of complementation, providing an overview of how theoretical syntax and acquisition studies may combine to broaden our knowledge about the topic. The articles are organized in two sections, each one followed by a comment paper: the first section, more theoretical in its nature, gathers contributions analyzing major syntactic aspects of complementation in Portuguese, from a synchronic and a diachronic point of view; the second section includes articles on L1 and L2 acquisition of Portuguese complementation. Both sections especially focus on infinitival structures; mood selection and the interpretation of subjects in finite complement clauses are also topics of particular relevance. The volume is meant for researchers and students interested in formal syntax and acquisition in general and Portuguese syntax and acquisition in particular.
